[18241]

hello im relativley new to php and have only been using it for the past two weeks or so, could anyone help me with this. im trying to verify some important text boxes on my form, but if there empty then i want it to appear with a message that says you have not typed anything in "this" text box, here is the code for the page.

this is the main part of the code where it is needed 🙂,

thanks in advance

First I don't fully understand your question. Have you tried doing a tutorial or search the manual for answers before posting here? You can read more tips for posting here.

Second I doubt that anyone will read all your code. If it's the same code repeated over and over again then post it only once, then people may help you out with that one and you have to do the same to the other parts as well.

thank you for the tips,

im using the code for an application form im creating, i would like it to verify if there are some wrong characters in the code which it does fine. i would also like it to verify if there is nothing in the text box at all, this is where it falls over, i can put anything in the text box and it will still give me an error code even if it has the right characters in it. here is each part of the code once.

checks the characters being used
function check_field1($field_name_1)
{
if(!preg_match("/[^{0-9\£]+$/s",$field_name_1))}
return TRUE;
else
return FALSE;
}
checks if it is empty (this is where the main problem lies)
$error=0;

if(!$field_name_1)
{
$error="1";
echo "you have not entered the amount required for this loan ";
}

gives a message if the wrong characters are used
if(!check_field1($amountrequired))
{
echo "you have put characters that are not allowed in the amount required text box ";
$error++; //$error=$error+1;
}
i have tried using other tutorials and websites but all to no avail.

i hope this is clearer for everyone.

thank you

hmm... 44 functions emcompassing 308 lines that I can quite easily reduce to 176 lines. Even then, it would probably be much longer than needed.

There is little point in having a function for each form field. Rather, make each function perform, well, a definite function. Instead of having check_field1(), check_field2(), ..., check_fieldN(), have more descriptive names, e.g. checkEmail(), checkValidName().

if (!empty($some_variable))
{
   echo "This is ok";
}
else
{
   echo "This sux";
}

I think that is what you are after.
