Array

[Dysan]

How do I insert data into an array, from a form?

[Barand]

Data from a form is already in $_GET or $_POST array depending on form method.

[Dysan]

Can you give me an example of how to insert data from a database, into an array?

[pocobueno1388]

It's in an array when you call it from the database.

 

<?php

$query = mysql_query("SELECT * FROM table");

//Make $row an array of DB values
$row = mysql_fetch_assoc($query);

//Now you can echo values out from the array
echo $row['val'];

?>

example:

 

$sql = mysql_query("SELECT * FROM data WHERE id=1");

$row = mysql_fetch_array($sql);

 

now you can do $row['column_1'], $row['column_2'] etc depending on how many columns you have

how do Shopping Karts work, how do they remember whats in your shopping Kart? How do I create a PHP Shopping Kart?

[pocobueno1388]

You need to use sessions to create a shopping cart. If you have all these questions, your obviously not ready to take on programming your own shopping cart. I suggest reading tutorials to learn the basics of PHP.

[Dysan]

What just sessions? So I don't need to use an array? Can sessions hold multiple values? - e.g. The contents of a shopping cart (Product, Cost etc)

[pocobueno1388]

Yes, a session can be an array.

[Dysan]

How do I do that? store an array as a session?

Can you give me an example of storing values from a form inside an array?

[Wes1890]

^ well, i would try to help you, but it would only lead to more endless questions.. use Google and search for your questions first.. google is truely amazing

[Dysan]

Try me! I know a fair bit about sessions, and a little bit about arrays. I just need to see an exmplae, in order to make it self explanatory.

Buy a PHP/MySQL book.

So how do I insert data into an array via a form?

[pocobueno1388]

<?php

$arr = array();

if (isset($_POST['submit'])){
   $arr[] = $_POST['var'];
   print_r($arr);
}

?>

<p>
<form method="post">
   <input type="text" name="var">
