form, <input type=(needs to accept an INT value?)

[Lylian]

Need help on the form below, where "XXXX" needs to be an INTEGER instead of "TEXT" anything else.

<form method="post" action="myphpfile.php">

<input type="xxxx" name="quantity">

<input type="submit" name = "submit" value="quantity">

There isnt an integer form field. You'll have to use text and use error checking to make sure the EU entered a numeric value.

Javascript or [man]is_numeric[/man]

it works, Thank you. Here, I post a reply for someone new like me might need it for reference!!

<form method="post" action="myphpfile.php">
<input type="text" name="quantity">
<input type="submit" name = "submit" value="add_a_number">
<?php
function convert_type( $quantity )
{
if( is_numeric( $quantity ) )
{

return (int)$quantity;
}

}
?>

I am sure some seniors had better way to do, but i share whatever I know.

Everyone starts somewhere, so don't let anyone crack on your code, just pick up on styles. Here's a suggestion:

 return abs($quantity); 

Will make sure that a negative number isn't permitted, it will turn it into a positive.

[man]abs[/man] - Absolute Value

Also, you don't need to cast your return as an integer, your is_numeric function verifies it is an integer.
