multidimensional arrays

[nevsi79]

my script worked, i was  jumping on my bed with joy, then I modified and now it does not work I just can't see why?!!!

 

here's my form:

http://geeks-fix.co.uk/wforms/form.html

 

now this is my code:

 

<?php

$cnt = count($_POST['wf_Relatives1']); 
// any field that 
//repeats(if you want to know how many repeats there are)

$fieldset = $_POST['wf_Relatives1']; 
$field = $_POST['wf_FirstName'];
//echo "$field";
$field2 =$_POST['wf_LastName'];
//echo "$field";
$field3 =$_POST['wf_BirthDate2'];
//echo "$field";

foreach ($fieldset as $c) {
	while (list($k, $v) = ($c)) {
	  echo "$k ... $v <br/>";
	  }
	}   

	   ?>

 

The first time it worked definitely with the $fieldset and after I added 3 times (first name, last name, dob) in the form, it did output the following:

 

0 ... some first name A

1 ... some first name B

2 ... some first name C

0 ... some last name A

1 ... some last name B

2 ... some last name C

0 ... some dob A

1 ... some dob B

2 ... some dob C

 

but now it is not working, instead prints out this:

Warning: Invalid argument supplied for foreach() in /home2/nevsi79/public_html/wforms/firstoutput.php on line 15

 

Can anyone see where the problem is:

 

I wonder how they are doing it here: http://www.formassembly.com/wForms/v2.0/documentation/examples/repeat.html

Foreach expects an array. You're giving it a string.

Yes but it worked the first time,

 

I found this in my book:

 

foreach ($fieldset as $c) {
	while(list($k, $v) = each ($c)) {
	echo "k ... $v <br/>";
	}
}

 

 

Anyhow, you might understand me better if I do the following (print_r the fields as they are arrays even if I do not repeat them with the repeat js behaviour as I added [] to the names of each field):

 

<?php

$cnt = count($_POST['wf_Relatives1']); 
// any field that 
//repeats(if you want to know how many repeats there are)

$fieldset = $_POST['wf_Relatives1']; 
$field = $_POST['wf_FirstName'];
print_r($field);
echo"<br/>";
$field2 =$_POST['wf_LastName'];
print_r($field2);
echo"<br/>";
$field3 =$_POST['wf_BirthDate2'];
print_r($field3);
echo"<br/>";

//foreach ($fieldset as $c) {
	//while(list($k, $v) = each ($c)) {
	//echo "k ... $v <br/>";
	//}
//}

	   ?>

 

and then I get this output:

 

Array ( [0] => some first name A [1] => some first name B [2] => some first name C )

Array ( [0] => some last name A [1] => some last name B [2] => some last name C )

Array ( [0] => some DOB A [1] => some DOB B [2] => some DOB C )

 

I do not insist in organising them in a multidimensional array, but my final go is t put them in mysql table.

 

MySql table will basically have 3 columns: first name, last name, DOB

 

and I want A, B & C to be different entries i.e. rows in my table, if that makes sense at all?

 

Can anyone help, please?

You didn't print_r the feildset variable... which happens to be the one you need to be an array, or foreach returns an error.

[nevsi79]

no it didn't work with print_r($fieldset)

 

it did work with my foreach earlier I was so happy, jumping on my bed with joy and then I messed it up, can't even see why

[discomatt]

that's your problem. For some reason, $fieldset is no longer an array, so your call to foreach($fieldset... returns an error
