Re: Re: syntax for checking if string contains something

Thanks for your reply. But I tried it and it seems to pass right through the if condition without checking if the string is empty or not. Here is another PHP file where I tried using the "empty" function The input form contains the following: <h2>QTY:</h2><input type="text" name="qty" size=7><br> Here is the part that checks whether or not the user has pressed "submit" and checks if "$qty" is empty or not: if (isset($submit)){ if (!empty($qty)) { echo "Please enter the quantity for your quotation enquiry.";} When nothing was filled in for $qty the if condition did not prompt me to enter a quantity. Any suggestions? thanks.
