[SOLVED] simple session Q...i think

[austin350s10]

I am trying to store the values a user entered into a form on my website so if they refresh the page to work they do doesn't disappear. Below is the code I am using on the form to store the values.

 

<?php
session_start();
if (isset($_SESSION['email'])){
   $email_value = "value=\"".$_SESSION['email']."\" ";
}
else{
   $email_value = "";
}
?>

 

This works great but it doesn't work for select lists.  How do I get a session to store a select list option value?

 

Thanks,

Exactly the same only in a select list you use the argument 'selected' within the option element i.e.

<select name="test">
<option value="1"<?php if($_SESSION['test'] == 1) print " selected"; ?>>1</option>
<option value="2"<?php if($_SESSION['test'] == 2) print " selected"; ?>>2</option>
</select>

To be honest I would have just used $_POST (after cleaning the values) and not $_SESSION for this task as the data is not persistent anywhere else except the page with the form.

 

i.e.

<select name="test">
<option value="1"<?php if($_POST['test'] == 1) print " selected"; ?>>1</option>
<option value="2"<?php if($_POST['test'] == 2) print " selected"; ?>>2</option>
</select>

If using sessions you will have to make sure you destroy all of the values otherwise if a user comes back to the form all of the values will still be pre-filled.

after cleaning the values

 

Not necessary in this case. You're just doing a comparison of two strings.

In this quick example, yes

 

But you wouldn't want tainted data being placed back into the form values i.e. HTML tags, script injection, etc
