textarea problem

shweta

hi all
i m facing a strange problem with textarea.
i want to grab html code in the textarea for editing purpose.
In that html code i have code for textarea. and when i click on the edit button to grab the html code from the file ...it is displaing code only upto textarea....and remaining code is parsing through the browser...and showing the output of that code in the same form...

following is my code...

<TD VALIGN="TOP" align="center" colspan=2>Additional Comments:<br>
<TEXTAREA NAME="comments" ROWS="5" COLS="50" Wrap="Virtual"></TEXTAREA><br>
<input checked type=radio name="rf" value="1" ><font face=arial size=2> Full Story in HTML  </font>
<input type=radio name="rf" value="0" ><font face=arial size=2> Link Only  </font>
<INPUT TYPE="hidden" NAME="url" VALUE="{url}">
<INPUT TYPE="submit" NAME="action" VALUE="Send">
</TD>
</TR>

now this code is in a tpl file. i want grab it in a textarea. but its only showing following code.....

<TD VALIGN="TOP" align="center" colspan=2>Additional Comments:<br>
<TEXTAREA NAME="comments" ROWS="5" COLS="50" Wrap="Virtual">

and instead of showing code of remaining part its showing
radio buttons and submit buttons on the form.

little bit confusing....right??

Are you using htmlspecialchars() to stop the browser from trying to render the HTML in the text area as HTML?

<textarea><?php echo htmlspecialchars($tpl)?></textarea>

hi
thanks for ur suggessions. i have used non html tags and its working fine. but...one problem remains..
In the .tpl file where i have all this html code i have included

now its working fine. but i need to parse this same template two times (.tpl file)
one with non html tags for displaing code as it is and secondly with the output.( not html code)

now when i use
<TEXTAREA NAME="comments" ROWS="5" COLS="50"></TEXTAREA>

my first script is showing me all the code in the textarea without parsing through the browser.
but my second script is showing code of textarea instead of showing textarea on the form.

now i can not write php in the tpl file. something like this..........
if($flag==0)
{
<TEXTAREA NAME="comments" ROWS="5" COLS="50"></TEXTAREA>
}
else
{
<TEXTAREA NAME="comments" ROWS="5" COLS="50"></TEXTAREA>
}

i m not getting what to do???

waiting for ur help as early as possible...

Didn't understand any of what you were trying to do there.

Try this out and see what it does:

<?php

$tpl = "<html><head><title>Sample Title</title><body>Sample Body</body></html>";

?>
<textarea><?php echo htmlspecialchars($tpl);?></textarea>

That should give you a few ideas how to proceed.

shweta

is it possible to parse a .tpl file through $tpl instead of directly giving html code??

coz i want to parse whole file...

If I understand you, your .tpl file contains html code. In that case, the answer is yes. I only used a literal html string in the example as an illustration. If you want to stick the contents of a file there feel free to do so.

What I think you need is an easy way to make your HTML code run in the browser or not run easily.
To make the code not run use htmlspecialchars() on the code you are putting in the textarea.
To convert this back to real code use this function

<?php
unhtmlspecialchars($text){
        $text=ereg_replace('&gt;', '>', $text); 
        $text=ereg_replace('&lt;', '<', $text); 
        $text=ereg_replace('&quot;', "\"", $text); 
        $text=ereg_replace('&amp;', '&', $text); 
//the first & is actualy an amersand symbol followed by the letters "amp"
//but this forum converts this to just &.  Change this after copying.
}
?>

If you dont already know the manual at has php.net user comments that are very helpful when learning about a function like this.

What I've found those is that the browser will do this itself when the form containing the textarea is submitted.

<?php
if(isset($_POST['text']))
   echo $_POST['text'];
?>
<html><body>
<form action='<?php echo $_SERVER['PHP_SELF']?>' method="post">
<textarea name="text"><?php echo htmlspecialchars($_POST['text'])?></textarea>
<input type="submit">
</form>
</body></html>

If you type < and > characters into the textarea, $_POST['text'] will contain < and > characters, and not < and >. And so will the textarea when it's rendered. Try it while entering something like <font color=red>Foo</font>.
