Real problems

[mellowmuppet]

I am trying to do some 'simple' validation: This is the code i am useing

<form action="" method="get">
<p>Please enter your name, </p><input type="text" name="name" />
<?php if (empty($_GET['name'])) 
{ 
echo "You must enter your name<"
} 
?>

//Some code emitted (same as above basically)


<input type="Submit" />
</form> 

 

If you look at the code it should, when nothing is put in the form flag up an error and display the text. it only displays a blank page though which is frustrating. Im fairly new to php and my lecturers code doesnt work either.

I use a Xampp setup and its all up and running and am configuring with notepad ++

 

 

After doing this i need to make sure that its > 3 characters but < 15 how would i implement this into the code on the same page.

 

Should i create a seperate .php page which does tihs part and leave the validation on the html form?

 

Thanks

Turn on error reporting so it returns errors

 

echo "You must enter your name<"

 

should be

 

echo "You must enter your name";

[micah1701]

if you're posting this form you need to use $_POST['name'] not $_GET['name']

 

 

EDIT: I withdraw my response, as I see you're setting the method to "get"

 

you are missing a colon after your echo statement though (as revraz pointed out)

[mellowmuppet]

echo "You must enter your name<"

 

is supposed to be  echo "You must enter your name</body></html>";  i think but i have updated the code for that

 

Im simply trying to create a form that will validate the information in that page before i take them to another page.

 

 

unless the requirements are met it will return an error message on the same page and ask the user to correct

 

so the field must have some data  and this data must be within the range of 3 - 15 characters long

If you don't want a blank page, as stated, turn on error reporting in your php.ini or using ini_set

[mellowmuppet]

I dont understand how to do that >.<

Like this:

 

<?php

// Set up error reporting.
error_reporting(E_ALL);
ini_set("display_errors","2");

?>

 

put it at the top of ALL your code.

[mellowmuppet]

I give up. no errors are being returned so im just going to ignore it.

<?php

 

// Set up error reporting.

error_reporting(E_ALL);

ini_set("display_errors","2");

 

?>

 

 

no errors reported

 

thanks for your help though. ive been pissing around with this for like 3 hours now an im just getting really angry

 

all i have to do is the following.

 

Produce a PHP page that validates data entered in the field. You should at a very minimum validate presence, length and range.

 

It just wont do what its told. funny im stuck on this cause ive done all the other stuff with SQLyog apache and everything. jsut really winds me up hence why i should never be a programmer

Does a simple page like

 

<?php

echo "hi";

?>

 

work?

[mellowmuppet]

yeh ive been writing code all day. just this is code is being a prick.

 

i did test the simple code though lol
