PHP Question

spacetrain · 06-23-2006, 03:28 PM

Hey,

I have the following code in a script:

PHP Code:

  <?php

if ( empty($tireqty) == 1 ) {

echo '<font color=#ff0000>';

echo 'You did not enter an amount for tires <br /><br />';

echo '</font>';

 
if ( empty($oilqty) == 1 ){

echo '<font color=#ff0000>';

echo 'You did not enter an amount for oil <br /><br />';

echo '</font>';

 
 
if ( empty($sparkqty) == 1 ){

echo '<font color=#ff0000>';

echo 'You did not enter an amount for spark plugs <br /><br />';

echo '</font>';

include 'orderform.html';

exit;

}

include 'orderform.html';

exit;

}

include 'orderform.html';

exit;

}

?>

What i want it to do is display a message when a value isnt entered into a field but i want to display an error for each missed field at once and if they arent there show the order form again instead of running the rest of the code. However with the code above if the first one exists it doesnt check for the rest of the statements and there must be an easier way than copying the next two into the else section?

Im learning php so i just want to know as i will probably use this in a future script.

Thanks

Something like this?

PHP Code:

  <?php

 
if (empty($tireqty))

{

    echo '<font color=#ff0000>You did not enter an amount for tires <br /><br /></font>';

    include 'orderform.html';

}

else if (empty($oilqty))

{

    echo '<font color=#ff0000>You did not enter an amount for oil <br /><br /></font>';

    include 'orderform.html';

}

else if (empty($sparkqty))

{

    echo '<font color=#ff0000>You did not enter an amount for spark plugs <br /><br /></font>';

    include 'orderform.html';

}

else

{

    // They are not empty

}

 
?>

That would only display one error at a time, but thanks.

I managed to find a solution and edit it a bit, the code i used was:

PHP Code:

  if ( empty($tireqty) == 1 || empty($oilqty) == 1 ||  empty($sparkqty) == 1 )

{

echo '<font color=#ff0000>';

echo 'You didnt enter the following fields: <br />';

if(empty($tireqty) == 1 )

   { echo 'tires<br />'; }

if(empty($oilqty) == 1 ){echo 'oil<br />'; }

if(empty($sparkqty) == 1 ){echo 'spark plugs<br />'; }

echo '<br /><br />';

include 'orderform.html';

exit;

}

Means it shows as:

You didnt enter the following fields
{lists every field not entered}
