&quot;Remembering&quot; User Input

"Remembering" User Input

jameseymour

I have a form that has a large amount of fields that use textboxes and listboxes. Each listbox is populated by different tables in a database, these listboxes have buttons and textboxes beside them to add new items to the tables that populates them. When a new item is added the form is refreshed so that the new item can be selected from the listbox. In doing this all user data is cleared so they must refill the form from the begining. I need a way to store the user data in somekind of global variable so that the form can be refreshed with the users data after an item is added to any of the listboxes.

What would be the easiest way to implement this?

a simple example:

<?php
$list_array = array(1,2,3,4,5);

if (isset($_POST['submit']))
{
	foreach ($_POST as $key => $value)
	{
		$$key = trim(stripslashes($value));
	}
}

echo '
<form action="" method="POST">
all these form fields retain their values after the form is submitted:<br><br>
text: <input type="text" name="text" value="'; if (isset($text)) {echo $text;} echo '"><br><br>
listbox: <select name="list">';
foreach ($list_array as $value) {echo '<option'; if (isset($list) && $list == $value) {echo ' selected';} echo '>' . $value;}
echo '</select><br><br>
checkbox: <input type="checkbox" name="checkbox" value="Y"'; if (isset($checkbox)) {echo ' checked';} echo '><br><br>
radio:
1. <input type="radio" name="radio" value="1"'; if (isset($radio) && $radio == 1) {echo ' checked';} echo '>
2. <input type="radio" name="radio" value="2"'; if (isset($radio) && $radio == 2) {echo ' checked';} echo '><br><br>
<input type="submit" name="submit" value="submit">
</form>
';
?>

Thanks for the help mate.

I tried your code by itself and that worked, but when trying to port it over to my code, it did not work. I was wondering if you could take a look at my code and show me how to implement it properly to atleast one textbox, then I can get everything else working myself. Below is my code, I took everything to do with your post out so it isn't in the way. I also had to take out some functions so that it would fit in here (only allowed 10000 chars).

Sorry if my code is kinda messy, I was constantly learning php throughout this whole page.

<?php
error_reporting(E_ALL);
if (isset($_POST['f_AddPersonnelButton']))
   {
      AddPersonnel();
   }
else if (isset($_POST['f_AddOSButton'])) 
       AddOS();
     else if (isset($_POST['f_AddApplicationSoftwareButton'])) 
            AddApplicationSoftware();
          else if (isset($_POST['f_AddDatabaseSoftwareButton'])) 
                 AddDatabaseSoftware();
               else if (isset($_POST['f_AddProject']))
                      AddProject();
                    else
