I’ve got a form with multiple sets of data (which are variable) which I’m attempting to pass into PHP and then for each group of fields, have the individual data into PHP variables ready so I can work with them

My form looks like this :

<input type="hidden" name="group[0]form[][familymember]" value="0">
<input type="checkbox" name="group[0]form[][requestchecked]" value="1">
<textarea name="group[0]form[][requestmessage]" ></textarea>                                                                           

    
<input type="hidden" name="group[1]form[][familymember]" value="30">
<input type="checkbox" name="group[1]form[][requestchecked]" value="1">
<textarea name="group[1]form[][requestmessage]" ></textarea>

    
<input type="hidden" name="group[2]form[][familymember]" value="31">
<input type="checkbox"  name="group[2]form[][requestchecked]" value="1">
<textarea name="group[2]form[][requestmessage]"></textarea>

And my PHP code is as below :

foreach ( $_POST['group'] as $group ) {
    
        foreach ( $group['form'] as $member) {
            $thisfamilymember = $member['familymember'];
            $thisrequestmessage = $member['requestmessage'];
            $thisrequestchecked = $member['requestchecked'];
        }
        
        echo "<br>thisfamilymember = ".$thisfamilymember;
        echo "<br>thisrequestmessage = ".$thisrequestmessage;
        echo "<br>thisrequestchecked = ".$thisrequestchecked;   
    }

However rather than getting 9 lines showing the various data thats been entered in the form, all the echo commands come back showing the variables are empty :

thisfamilymember =
thisrequestmessage =
thisrequestchecked =
thisfamilymember =
thisrequestmessage =
thisrequestchecked =
thisfamilymember =
thisrequestmessage =
thisrequestchecked =
