If statements to assign POST variables

[Omzy]

I find myself doing this a lot of the time:

 

if(isset($_POST['name'])) $name=$_POST['name'];

 

I get the feeling there is a simpler way of doing this. It's not such a bother if it's just one or two but its when you have a whole bunch of these that it gets tedious!

you can use the ternary operator

 $name = (isset($_POST['name'])) ? $_POST['name'] : null;

 

but thats not much better. Assuming you want to always check if the post variable is set before you assign it to a variable, i don't see a better way than an if statement

forms name is "add"

if (isset($_POST['add'])){
$var = $_POST['value'];
$var2 = $_POST['value2'];
$var3 = $_POST['value3'];
}

well, that script doesn't add them, but just showing you the simplicity

One alternative, have an array of form element names then loop through that assigning the data.

 

$validElements = array("name", "email", "user", "password");

foreach ($validElements as $val) {
       $$val = isset($_POST[$val]) ? $_POST[$val] : null;
}

 

Which way is better is up to you to decide.

You could create a function

 

<?php

function setValue (&$variable, $default)
{
    return (isset($variable)) ? $variable : $default;
}

//Set values for testing only
$foo['bar1'] = 'Passed Value';
//$foo['bar2'] = 'Passed Value'; //This value not set


$bar1 = setValue($foo['bar1'], 'Value not set');
$bar2 = setValue($foo['bar2'], 'Value not set');

echo "bar1 = $bar1";  //Output: bar1 = Passed Value
echo "bar2 = $bar2";  //Output: bar2 = Value not set

?>
