echo in form input value

Sep 9th, 2009

This is driving me crazy and should be very easy. I am trying to pre-fill an html form with session data using echo. I can compile and run but the form field contains a / if the session data is blank. How can I get rid of the /

Heres the code:

<input name="fname" type="text" class="textfield" id="fname" value = <?php echo $_SESSION["namevalue"]; ?> />
<input name="fname" type="text" class="textfield" id="fname" value = <?php echo $_SESSION["namevalue"]; ?> />

I have tried several combinations of '"` etc and it seems I am just missing the obvious. Thanks in advance - anyone.

Hi andym67 and welcome to DaniWeb

A better approach is this:

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
if(isset($_SESSION["namevalue"]))
   $val = $_SESSION["namevalue"];
else
   $val = "";
// maybe do some validation on $val here
echo "<input name='fname' type='text' class='textfield' id='fname' value='$val' />";
if(isset($_SESSION["namevalue"]))
   $val = $_SESSION["namevalue"];
else
   $val = "";
// maybe do some validation on $val here
echo "<input name='fname' type='text' class='textfield' id='fname' value='$val' />";

or:

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
<?php
if(isset($_SESSION["namevalue"]))
   $val = $_SESSION["namevalue"];
else
   $val = "";
// maybe do some validation on $val here
?>
<input name="fname" type="text" class="textfield" id="fname" value="<?php echo $val; ?>" />;
<?php
if(isset($_SESSION["namevalue"]))
   $val = $_SESSION["namevalue"];
else
   $val = "";
// maybe do some validation on $val here
?>
<input name="fname" type="text" class="textfield" id="fname" value="<?php echo $val; ?>" />;

There are no stupid questions, only those too stupid to ask for help.
echo is a web developer's best friend.

Look at your value attribute,:

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
value = <?php echo $_SESSION["namevalue"]; ?> />
value = <?php echo $_SESSION["namevalue"]; ?> />

This should be:

value="<?php echo $_SESSION["namevalue"]; ?>" />

AJAX is not a programming language, scripting language or any other sort of language.
It is acheived by using JavaScript http functions.
So, AJAX = JavaScript.

Agree with Xan's code fix

embedding php inside html, it is important to get all the quotes in.
only add a usefula(maybe) caveat to the code he provided, a recommendation to change whatever editor used to something that code highlights
It becomes easy to see when something is missing if the text is some bright colour when a(the) quote(s) Brace(s) Bracket(s) < > is(are) missing
Notepad++ Notepad2 & a bunch of good code highlighting editors

without the quotes output html for a nul field is value= /> your visble backslash
with quotes a nul gives value="" />

Failure is not an option It's included free, you don't have to do anything to get it
If at first you dont succeed, join the club
Of course its always in the last place you look, you dont keep looking after you find it

Please mark solved problems, solved

Hey All - Thanks for the several different suggestions. I am using

 Help with Code Tags 
 PHP Syntax (Toggle Plain Text) 
if(isset($_SESSION["namevalue"]))
if(isset($_SESSION["namevalue"]))

but was able to determin that the previously mentioned part was where I was messing up so hence my limited code post.

I am still getting used to PHP and NetBeans both so the color scheme/code completion and the exact ;,'"` where have you was throwing me off.

Thanks again.!

Andy
