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.
