in the code window is my code to sdisplay a form that allows a user to edit information, the last diaplayed form element is the Expiry date field, I have tried all sorts of ways to format it so that it displays as DD-MM-YYYY , but no luck, I am probably missing something simple.

Where does the date_format function come into play , before the form code or in the form element below?

<p>
            <label for="Expiry">Expiry <em>*</em></label>
            <input name="Expiry" id="Expiry" size="25" maxlength="100" class="required" value="' . $row_user_edit['Expiry'] . '"/>
            </p>

thanks in advance.
$user_edit = '<div><form id="edituser" method="post"><input type="hidden" name="action" value="updateuser">		
		<fieldset>

		<p>
		<label for="name">Name <em>*</em></label>
		<input id="name" name="name" size="25" maxlength="255" class="required" value="' . $row_user_edit['name'] . '"/>
		</p>

		<p>
		<label for="local_authority_id">Local Authority <em>*</em></label>
		<select style="width:175px;" name="local_authority_id" id="local_authority_id" value="' . $local_auth_name['la_name'] . '">			
			'.$local_authority_option.'
		</select>
		</p>

		<p>
		<label for="school_learning_est_id" >School or Learning Establishment name <em>*</em></label>
		<select style="width:175px;" name="school_learning_est_id" id="school_learning_est_id" value="' . $school_name['School'] . '">'.$tblschool_new_option.'</select>
		</p>

		<p>
		<label for="email">E-Mail <em>*</em></label>
		<input id="email" name="email" size="25" maxlength="100" class="required email" value="' . $row_user_edit['email'] . '"/>
		</p>

		<p>
		<label for="telephonenumber">Telephone Number <em>*</em></label>
		<input name="telephonenumber" id="telephonenumber" size="25" maxlength="100" class="required" value="' . $row_user_edit['telephonenumber'] . '"/>
		</p>

		<p>
		<label for="Expiry">Expiry <em>*</em></label>
		<input name="Expiry" id="Expiry" size="25" maxlength="100" class="required" value="' . $row_user_edit['Expiry'] . '"/>
		</p>

		<p>
		<input class="submit" type="submit" value="Submit"/>
		</p>
    </fieldset></form></div>';

http://php.net/manual/en/function.date.php 

<input name="Expiry" id="Expiry" size="25" maxlength="100" class="required" value="' . date("d/m/y", $row_user_edit['Expiry']) . '"/>

<input name="Expiry" id="Expiry" size="25" maxlength="100" class="required" value="' . date("d/m/Y", strtotime($row_user_edit['Expiry'])) . '"/>

The date() function requires an integer for its second parameter, strtotime() returns the integer.

It all depends on how you store that Expiry date.

I currently store all date/time based columns as integer values (unix timestamps) when using mySQL/PHP.

If it is stored as a unix timestamp, use the function date("d-m-Y, $row_user_edit['Expiry']) to format the timestamp loaded from database.

If stored as a mySQL datetime field, you'll need to make a function to convert MySQL's standard datetime format of YYYY-MM-DD to DD-MM-YYYY

Since you have another question open to ask abotu storing a date in format DD-MM-YYYY in a mysql date field, I will now assume that this is what you will need.

Look at these functions to swap sequence of the dates in a string:


function MysqlToPhpDate ($string) {
  $arr = explode('-', 'string) // array nog is like this: $arr[0] = '2010'; $arr[1] = '09'; $arr[2] = '08';
  $datePhp = $arr[2].'-'.$arr[1].'-'.$arr[0];
 
  return $datePhp;
}

function PhpToMysqlDate ($string) {
  $arr = explode('-', 'string) // array nog is like this: $arr[0] = '08'; $arr[1] = '09'; $arr[2] = '2010'
  $dateMysql = $arr[2].'-'.$arr[1].'-'.$arr[0];
 
  return $dateMysql;
}

You will need to do check/correction of the input field, since users can input it as a string and who knows how they will format the inputted date.

No offense meant to johnwarde, but strtotime() can also return FALSE.  That's why you might want to read the article I posted.
