Remove the highlighted character on this line

        if(strlen($field) > 3) && (strstr($field)){

[Philip]

if(strlen($field) > 3) && (strstr($field)){

 

if(strlen($field) > 3 && strstr($field)){

 

Notice the parenthesis.

when i changed it i got Warning: Wrong parameter count for strstr() in C:\xampp\htdocs\val.php on line 13

[Danny620]

let me get this right does strstr() check if its and string and checks if it contains any numbers

[Philip]

No?

 

strstr in the manual - maybe you should look at that

[Danny620]

oh lol then whats the one to check if its a string and does'tn contain any numbers

[Philip]

I dont think there is one that will default check to make sure there aren't any numbers in it - since a string can contain numbers.

 

is_string[/code] ?

//Function val validates form submissions by;
//Striping html tags from from;

function val($field = false){
			global $dbc;
