通常情况下,re-加在以辅音或者虚音h为首字母的动词前:

remarier - 使再婚

(加在marier - 使结婚前)

rehausser - 再提高

Res-

在以s开头的动词前,re-常常为res-

ressortir - 再出来

(加在sortir - 出来前)

ressembler - 相似

Ré- and r-

在元音或者哑音h前,re-要么加上一个变成ré(在拉丁词根的单词中尤其如此),要么缩写成r-,对于个别动词,这两种情况都存在。

Send variables between Javascript, Form and PHP on the same page



Super useful bits of PHP, Form and JavaScript code
















All code on this page is considered by us to contain the most basic and
important aspects of form sending. This page basically shows in the
shortest possible way how you can:

  • Test your PHP offline - Test your PHP pages offline easily, without installing your own web server.








  • Send variables between Javascript, Form and PHP on the same page:








  • Send variables from one page to another:









  • * URL variables to PHP/JavaScript page - Allow
    sending different variables via the URL string to the new page (readable
    through PHP or Javascript). This is more appropriate than the below if
    there are few pieces of small info you wish to send.

    * PHP variables to PHP page - Alternatively, maintain a session by sending PHP variables to another page with PHP in (allows super large arrays).

    * Form variables to PHP page - Alternatively, allow sending hidden form variables to a PHP page. This allows the user to (more easily than the above methods) select options on the page (via URL, radio buttons, or dropdown menu), and for these to be sent to the new page.

    * Form variables (tick boxes) to PHP page - As above but with tick boxes.






  • Dynamically update HTML - Allow different bits of HTML to dynamically execute according to user input:





















  • Send variables between Javascript, Form and PHP on the same page:





    PHP variable to Javascript variable:


    <?php   $myvar=10;   ?>
    
     <script type="text/javascript">
      jsvar = <?php echo $myvar; ?>;
      document.write(jsvar);  // Test to see if its prints 10:
     </script>
    


    Form variable to Javascript variable:


    <form name="myform4">    <input type="hidden" name="formvar" value="100">     </form>
    
     <script type="text/javascript">
      jsvar = document.myform4.formvar.value;
      document.write(jsvar) // test
     </script>
    





    PHP variable to Form variable:


    <form name="myform4">
      <input type="hidden" name="formvar" value="<?php phpvar=10; echo phpvar; ?>"> // PHP code inside HTML!!
     </form>
    




    Javascript variable to Form variable:


    <form name="myform3">
      <!-- It needn't be a "hidden" type, but anything from radio buttons to check boxes -->
      <input type="hidden" name="formvar" value="">
     </form>
    
     <script type="text/javascript">
      jsvar=10;
      document.myform3.formvar.value = jsvar;
     </script>
    


    Javascript variable to PHP variable:


    This is impossible (unless you reload the page), since all PHP code is
    rendered first (on the server side), and then Javascript is dealt with
    afterwards (on the client side).





    Form variable to PHP variable:


    Impossible like above.

























    Allow sending different variables via the URL string to the new page (readable through PHP or Javascript).



    The version shown below uses PHP to read the variables back, but it's
    possible to use Javascript and some messy splitting to do the same (for
    that route, see this nice little function, or here, or here for example code.)




    EXAMPLE:



    Send variables via URL!


    INSIDE "page1.php" or "page1.html"


    // Send the variables myNumber=1 and myFruit="orange" to the new PHP page...
     <a href="page2c.php?myNumber=1&myFruit=orange">Send variables via URL!</a> 
    
     


    INSIDE "page2c.php"

    <?php
      // Retrieve the URL variables (using PHP).
      $num = $_GET['myNumber'];
      $fruit = $_GET['myFruit'];
      echo "Number: ".$num."  Fruit: ".$fruit;
     ?>
     





























    Maintain a session by sending PHP variables (including multiple full
    blown multi-dimensional arrays if you so wish) to a page with PHP in.



    INSIDE "page1.php"

    <?php
     // "session_register()" and "session_start();" both prepare the session ready for use, and "$myPHPvar=5"
     // is the variable we want to carry over to the new page. Just before we visit the new page, we need to
     // store the variable in PHP's special session area by using "$_SESSION['myPHPvar'] = $myPHPvar;"
     session_register();
     session_start();                      
     $myPHPvar=5;
     $_SESSION['myPHPvar'] = $myPHPvar;
    ?>
    
    <a href="page2.php">Click this link</a>, and the "$myPHPvar" variable should carry through.
    



    INSIDE "page2.php"

    <?php
     // Retrieve the PHP variable (using PHP).
     session_start();
     $myPHPvar = $_SESSION['myPHPvar'];
     echo "myPHPvar: ".$myPHPvar." ..........(should say \"myPHPvar: 5\")<br>";
    ?>
    















    Allow sending hidden form variables to a PHP page. This allows the
    user to select options on the page, and for these to be carried across
    to the new page.



    EXAMPLE:



    (these links all go to the same PHP page...)

    Click 1st

    Click 2nd

    Click 3rd




    Click 1st

    Click 2nd

    Click 3rd
















    INSIDE "page1.php" or "page1.html"


    <!-- Pass over to the new page an arbitrary value, which in this case, is determined by... -->
    
    
    <!-- ***********  the link being clicked: (USE THIS OR...) ************** -->
    
    <a href="#" onclick="document.myform.formVar.value='first'; document.myform.submit(); return false">Click 1st</a><br>
    <a href="#" onclick="document.myform.formVar.value='second'; document.myform.submit(); return false">Click 2nd</a><br>
    <a href="#" onclick="document.myform.formVar.value='third'; document.myform.submit(); return false">Click 3rd</a><br>
    
    <!-- ***********  the radio button pressed before clicking "Send Form" (...OR USE THIS OR...) ************** -->
    
    <input name="br" type="radio" onClick="document.myform.formVar.value='first'">Click 1st<br>
    <input name="br" type="radio" onClick="document.myform.formVar.value='second'">Click 2nd<br>
    <input name="br" type="radio" onClick="document.myform.formVar.value='third'">Click 3rd<br><br>
    
    <!-- *********** the dropdown menu selected before clicking "Send Form" (...OR USE THIS) ************** -->
    
    <select onchange="document.myform.formVar.value=this.value">
     <option value="first">Select 1st</option>
     <option value="second">Select 2nd</option>
     <option value="third">Select 3rd</option>
    </select>
    
    <!-- ***************************************** -->
    
    
    <!--  In each of the above three cases, the hidden variable in the code below is needed for it all to work.
    Also notice how the destination page is given here, rather than in anything above -->
    
    <form method=post name="myform" action="page2.php">
     <input type="hidden" name="formVar" value="">
     <input type="submit" value="Send form!">
    </form>
    
    


    INSIDE "page2.php"

    <?php
     // Retrieve the hidden form variable (using PHP).
     $myvar = $_POST['formVar'];
     echo "myvar: ".$myvar;
    ?>
    









    Allow sending hidden form variables (using tick boxes) to a PHP
    page. This allows the user to select options on the page, and for these
    to be carried across to the new page.


    EXAMPLE:

    INSIDE "page1.html"


    Tick A

    Tick B

    Tick C









    CODE:


    INSIDE "page1.html"

    Tick A <input type="checkbox" checked onClick="document.myform2.a0.value = this.checked"><br>
    Tick B <input type="checkbox" onClick="document.myform2.b0.value = this.checked"><br>
    Tick C <input type="checkbox" onClick="document.myform2.c0.value = this.checked">
    
    <form method=post name="myform2" action="page2b.php">
     <input type="hidden" name="a0" value="true">
     <input type="hidden" name="b0" value="false">
     <input type="hidden" name="c0" value="false">
     <input type="submit" value="Send form!">
    </form>
    

    INSIDE "page2b.php"

    <?php
     // Retrieve the hidden form variable (using PHP).
     $myvarA = $_POST['a0'];
     $myvarB = $_POST['b0'];
     $myvarC = $_POST['c0'];
     echo "myvarA: ".$myvarA."<br>";
     echo "myvarB: ".$myvarB."<br>";
     echo "myvarC: ".$myvarC;
    ?>
    
















    Allow different bits of HTML to dynamically execute according to which radio button is pressed

    This is useful for many purposes including using buttons to change the
    picture (as part of a gallery), or for different sub forms to appear
    accordingly.



    EXAMPLE:





    Click 1st

    Click 2nd

    Click 3rd



    Anything can go here



    .....[I am the footer]







    CODE:

    <script type="text/javascript">
     function SetHTML1(type) {
      document.getElementById("a1").style.display = "none"
      document.getElementById("b1").style.display = "none"
      document.getElementById("c1").style.display = "none"
      // Using style.display="block" instead of style.display="" leaves a carriage return
      document.getElementById(type).style.display = ""
     }
    </script>
    
    <input name="br" type="radio" checked onClick="SetHTML1('a1')">Click 1st<br>
    <input name="br" type="radio" onClick="SetHTML1('b1')">Click 2nd<br>

    .....[I am the footer] <!-- Not needed, but shows how stuff below the dynamic content makes it move up and down -->
    







    Allow different bits of HTML to dynamically execute according to which dropdown menu is selected


    EXAMPLE:






    Anything can go here



    .....[I am the footer]





    CODE:

    <script type="text/javascript">
     function SetHTML2(type) {
       document.getElementById("a2").style.display = "none"
       document.getElementById("b2").style.display = "none"
       document.getElementById("c2").style.display = "none"
       // Using style.display="block" instead of style.display="" leaves a carriage return
       document.getElementById(type).style.display = ""
     }
    </script>
    
    <select onchange="SetHTML2(this.value)">
     <option value="a2">Select 1st</option>
     <option value="b2">Select 2nd</option>
     <option value="c2">Select 3rd</option>
    </select>
    
    <span id="a2" style="display:none">Anything can go here                                                 </span>
    <span id="b2" style="display:none">...like an image...<br><img src="http://www.skytopia.com/ar.png">    </span>
    <span id="c2" style="display:none">...<a href="http://www.skytopia.com">or a link</a>...                </span>
    
    .....[I am the footer] <!-- Not needed, but shows how stuff below the dynamic content makes it move up and down -->
    








    Add/remove bits of HTML according to multiple checkboxes


    EXAMPLE:







    Anything can go here









    CODE:

    <script type="text/javascript">
     function SetHTML3(check,type) {
      if(check==true) document.getElementById(type).style.display = "";
      else            document.getElementById(type).style.display = "none";
     }
    </script>
    
    <input type="checkbox" CHECKED onClick="SetHTML3(this.checked,'a3')">
    <input type="checkbox" onClick="SetHTML3(this.checked,'b3')">
    <input type="checkbox" onClick="SetHTML3(this.checked,'c3')">
    
    <span id='a3'> <b> Anything can go here </b></span>
    <span id='b3' style="display:none"> <b> ...like an image... <img src="http://www.skytopia.com/ar.png"> </b></span>
    <span id="c3" style="display:none"> <b> ...<a href="http://www.skytopia.com">or a link</a> </b></span>
    









    Test your PHP pages offline easily, without installing your own web server.

    This was something recently that doubled my productivity in a snap. Simply use EasyPHP.
    It's only 8 megabyte, and a million times quicker and simpler to
    install/configure than a fully blown Apache (or equivalent) server. In
    fact, it's small GUI window will make it instant - just make sure you
    put PHP pages inside its special www folder, and point your browser to
    the "http://127.0.0.1/mywebpage.php".



    Apart from this amazing time saver, always "View source" to see what PHP
    outputs to the HTML/Javascript page (remember, PHP is read by the
    server, but is not potentially visible to the visitor in the same way
    that Javascript or HTML is).



    The last amazing tip is to insert "exit();" when an annoying bug creeps
    into the code to see where the code goes wrong (try "exit()" at
    different points throughout the code)

    Mysql Problems with error 1100: Table ... was not locked with LOCK TABLES

    When you use LOCK TABLES, you must lock all tables that you are going
    to use in your queries. Because LOCK TABLES will not lock views, if
    the operation that you are performing uses any views, you must
    also lock all of the base tables on which those views depend.
    While the locks obtained with a LOCK TABLES statement are in effect,
    you cannot access any tables that were not locked by the statement.
    Also, you cannot use a locked table multiple times in a single
    query.
