echo in form input value

Expand Post »

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:

PHP Syntax (Toggle Plain Text)
 
<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.

Re: echo in form input value

Hi andym67 and welcome to DaniWeb

A better approach is this:

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:

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; ?>" />;

Re: echo in form input value

Look at your value attribute,:

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

This should be:

php Syntax (Toggle Plain Text)

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

Re: echo in form input value

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="" />

Re: echo in form input value

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

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
