uploading more than what is allowed

I have a section on my form called "Personal Details" - the max length is set to 250. My database field is set to varchar(250). what happens if some how a user tries to upload 260 characters. What would happen (lets say that i have no JS or php validation... the only validation is the maxlenght in the form) so what would happen

 

Depends. It will most likely be truncated by your database system.

 

You can check the length of the data submitted using strlen() eg
if (strlen($_POST['info'] <= 250))

 

you mean:
if (strlen($_POST['info']) <= 250)

 

Yes, i do, that's what not paying attention gets you:|

 

If the maxlength of the field is set to 250, how could you receive longer length on the server anyway?

 

<form method="post" action="http://yourserver.com/yourscript.php">
<input type="text" name="somename" length="251" />
</form>
