php array from posted form data

[ejscottb]

####### SORRY, MY TITLE SHOULD BE: PHP ARRAY FROM DATA - I'm not wanting to use POSTED FORM DATA, I'm using dynamic data called from a database. I just included the form elements here so users could see how the script processes posted data. #######

So I've got this form using a class function. Only I don't want to use the form. I'm just going to call data from a couple of database tables and process it to input into another database, so no posted values. I know I only need 'myfield_2', which will have a dynamic value, and all the others ('myfield_1' and 'myfield_3') will be equal to nothing. I have to use the class unaltered.

How can I express $postFields["myfields"] = array(), much like I've done for $lists? My head hurts much.

The form fields would look like this:

        <input type="text" name="myfield_1" value="" />             
        <input type="text" name="myfield_2" value="B" />            
        <input type="text" name="myfield_3" value="" />

Form processor:

PHP Code:

$contactFields = array();
    $contactFields["email_address"] = "bob@here.com";
    $contactFields["first_name"] = "Bob";
    $contactFields["last_name"] = "Smith";
 
    $contactFields["lists"] = array("http://pathtolist.com/contactlistID");
    
    $contactFields["myfields"] = array();
        foreach($_POST as $key=>$val) {
            if (strncmp($key, 'my_field_', strlen('my_field_')) === 0) {
                $contactFields["myfields"][substr($key, strlen('my_field_'), strlen($key)-1)] = $val;
            }
        }

PHP Code:

$field1 = $_POST['myfield_1'];
$field2 = $_POST['myfield_2'];
$field3 = $_POST['myfield_3'];
$my_fields=array($field1,$field2,$field2); 


I think that should do it.

There are no posted values - I won't be using the form. I just included it here as it applied to the form processor. I will only need myfield_2 and its value $var, but I assume I have to express the other 2 fields in the array statement (???) Something like below (neither of which work):

PHP Code:

$contactFields["myfields"] = array(myfield_1=> "", myfield_2=> "$var", myfield_3=> "");

// OR MAYBE

$contactFields["myfields"][1] = "";
$contactFields["myfields"][2] = $var;
$contactFields["myfields"][3] = "";

If you want to treat these all as an array, then you do as such. Change this:

        <input type="text" name="myfield_1" value="" />             
        <input type="text" name="myfield_2" value="B" />            
        <input type="text" name="myfield_3" value="" />

to this:

        <input type="text" name="myfield[1]" value="" />             
        <input type="text" name="myfield[2]" value="B" />            
        <input type="text" name="myfield[3]" value="" />

And access in PHP now becomes:

PHP Code:

$_POST['myfield'][1] 


For example. You can use whatever names or values you want for the index.

I got it - in case anybody ever needs this, the solution is:

PHP Code:

$contactFields["myfields"] = array(1=> "", 2=> $var, 3=> ""); 


Note no quotes surrounding the $var in array definition.
