Thanks everyone! Much love

[[SOLVED] verify input]

This is a small issue I believe, but I just can't get it right. Please help.

 

I'm like to store login info for new users. This script should check user input and if empty, should return error msg and not save anything on the database table. But my code saves whatever is sent even if some sections are empty. What should I do?

 

if ($name == "") {
$error .= "Enter your name";
}
if ($username == "") {
$error .= "Enter username";
}
if($password == "") {
$error .= "Enter password";
}
else {
$query = "insert into 'login' values()";

 

I have shortened to get to the point. If I only use one 'if' and one 'else' statement it works well. What can I do?

Say you have two forms on a page that gather different information. How do i make sure that script working on a particular form is called when the other form is submitted? Do I use,

[Accessing checkbox values]

$days is a variable that holds the values of a checkbox accessed through $_GET['days'];

'days' is an array of values that have been checked by user in a checkbox set.

[Error message]

 

What am I doing wrong here?

 

<body>

<?php

if (isset($_POST['submit'])){

$food=$_GET[food];

if (!empty($food)) {

echo "The foods selected are:<br />";

foreach($food as $foodstuff) {

echo $foodstuff.", ";

} else {

echo('check a box please');

}

}

}

?>

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">

<fieldset>

<label>Italian <input name="food[]" type="checkbox" value="Italian" checked /></label>

<label>Mexican <input name="food[]" type="checkbox" value="Mexican" /></label>

<label>Chenese <input name="food[]" type="checkbox" value="Chenese" /></label>

</fieldset>

<input type="submit" value="submit" name="submit">

</body>

[Accessing checkbox values]

Well the script is pretty long but heres a picture:

 

a user needs to state what days he's available to work. Let's say he is available Friday and Monday. The table handlin user info has one spot to store these days. so first i capture user selection as $days=$_get['days'] and insert into `table` as $days. when i check user input in the table, it shows "array". Can i have something like Friday, Monday?
