Question

I have never done anything like this, and I would like to know how to do it. I need to put 4 inputs into a sub array if it is field out

I know that when i $_POST the form to the server it sends the names of the inputs but how do I get the input to be allowed to have the same name

for example

the sub array i need it to be in is offers
here is what i dont know. How do i get the following inputs

<input name="offers[]['minspend']" value="15.00"/>
<input name="offers[]['minspend']" value="5.00"/>

<input name="offers[]['minspend']" value="19.00"/>
<input name="offers[]['minspend']" value="8.00"/>

<input name="offers[]['minspend']" value="30.00"/>
<input name="offers[]['minspend']" value="7.00"/>

<input name="offers[]['minspend']" value="100.00"/>
<input name="offers[]['minspend']" value="10.00"/>

is this correct or wrong?

thanks

Answer 1

This form

<input name="offers['minspend'][]" value="15.00"/>
<input name="offers['minspend'][]" value="5.00"/>

<input name="offers['minspend'][]" value="19.00"/>
<input name="offers['minspend'][]" value="8.00"/>

<input name="offers['minspend'][]" value="30.00"/>
<input name="offers['minspend'][]" value="7.00"/>

<input name="offers['minspend'][]" value="100.00"/>
<input name="offers['minspend'][]" value="10.00"/>

on doing var_dump($_POST) [assuming form method=post] give:

array(1) {
    ["offers"] = > array(1) {
        ["\'minspend\'"] = > array(8) {
            [0] = > string(5)"15.00"
            [1] = > string(4)"5.00"
            [2] = > string(5)"19.00"
            [3] = > string(4)"8.00"
            [4] = > string(5)"30.00"
            [5] = > string(4)"7.00"
            [6] = > string(6)"100.00"
            [7] = > string(5)"10.00"
        }
    }
}

So, that is how you do it.

you can remove 's around minspend. they aren’t needed.

You were almost there. offers[]['minspend'] means that you get:

array(){
    array(){
        'minspend' => "15.00"
    }
    array(){
        'minspend' => "5.00"
    }
    .. and so on
}

So what is happening is, when you do something like arr[] = 1, 1 is inserted into array arr.
