[RESOLVED] Keeping posted values from form

MitchEvans

I have a simple form and when the "Submit" button is pressed I still want the search box to contain the value as well as it echoing as it is.

<?

echo"<FORM action='' method='POST'>
<LABEL for='search'>Enter Post Code: </LABEL>
<INPUT type='text' name='search'>
<INPUT type='submit' value='Submit'>
</FORM>";

foreach ($_POST as $field)
{
	echo $field;
}


?>

Thanks for looking! 🙂

<?
$search = $_POST['search'];
echo"<FORM action='".$_SERVER['PHP_SELF']."' method='POST'>
<LABEL for='search'>Enter Post Code: </LABEL>
<INPUT type='text' name='search' value='$search'>
<INPUT type='submit' value='Submit'>
</FORM>";

foreach ($_POST as $field)
{
    echo $field;
}


?>

Never thought it could be so easy thankyou so much, How would I do it to keep it for a checkbox then? So if it's checked it stays checked

input type='checkbox' name='carpet_cleaning'> Carpet Cleaning

Something like this:

echo '<input type="checkbox" name="carpet_cleaning"'
    . (!empty($_POST['carpet_cleaning']) ? 'checked="checked"' : '') . '> Carpet Cleaning';

is how I usually handle checkboxes.

Note that you should be making sure these POST elements exist (via [man]empty/man, [man]isset/man, etc.) before you try to use them.

Cheers for that, but unfortunately my page won't load now I just get a blankl screen so i presume something may be slightly incorrect. Can you see why this would be?

echo"<td><input type='checkbox' name='carpet_cleaning' 
' . (!empty($_POST['carpet_cleaning']) ? 'checked="checked"' : '') . '> Carpet Cleaning </td>";

Yeah - your quotes don't match (as you can tell by looking at the syntax highlighting).

I almost always use single quotes as my string delimiters, so when I whipped out the above code sample... that's what I used.

You need to pick a string delimiter (single or double qutoes?) and make sure you start and end the string pieces with that same delimiter. Then, make sure you've escaped that delimiter if it appears inside the string.
