Javascript + PHP

@shaoen01Aug 24.2005

I am trying to assign a php variable to take the value from a textbox and i tried to transfer the value from the textbox to the php variable in javascript embedded inside a php script.

Apparently, it is not working and i must be doing something wrong. Can someone help me out here? Thanks

@shaoen01authorAug 24.2005 — #Sorry. Okay basically i have a textbox1 in my form and i want to assign a php variable (called A) to take textbox1 value. And both textbox1 and A php variable is in the same form or script. How do i do that in php coding?

Are you follow me better?

@MauAug 24.2005 — #You first need your form with textbox1 in it:

<i>
 </i>&lt;form action="&lt;?php print $_SERVER['PHP_SELF']; ?&gt;" method="post"&gt;
 &lt;textarea name="textbox1"&gt;&lt;/textarea&gt; &lt;!-- your text box --&gt;
 &lt;/form&gt;

Next, you need your PHP code. Because this form is being submitted as a "post" request, all the data in this form will appear in the superglobal, $_POST.

[code=php]
 if (!empty($_POST['textbox1'])) $textbox1 = $_POST['textbox1']; // this line fills $textbox1 when there is something to fill it with (that's what the if statement is for).  If no data was sent through POST, then $textbox1 doesn't change
 [/code]

So, your completed script looks something like this:

[code=php]
 <?php
 if (!empty($_POST['textbox1'])) $textbox1 = $_POST['textbox1']; // this line fills $textbox1 when there is something to fill it with (that's what the if statement is for).  If no data was sent through POST, then $textbox1 doesn't change
 ?>
 
 <form action="<?php print $_SERVER['PHP_SELF']; ?>" method="post">
 <textarea name="textbox1"></textarea> <!-- your text box -->
 </form>
 [/code]

I think that's what you are asking. Let us know if it works or doesn't ?

Untested.

I know this code below will help set the value of the input value for me:

[Code]
 <input type="text" id="zipfilename" name="zipfilename" value="<?php echo $zipfilename ; ?>">
 [/Code]

Is there anyway i can edit the current value of my input, zipfilename, later after i have inserted the code above?

I have tried to edit the value by using javascript but it does not show when i right click on IE and view source. Do you know why it is so?

[Code]
 echo '<script language="JavaScript" type="text/javascript" >' ;
 echo "document.downloadForm.zipfilename.value='".$zipfilename."'" ;
 echo '</script>' ; 
 [/Code]
