Argument should be an array

[assgar]

Hi

I thought I had resolved this problem but I am intermittently
the receving the warnings below.

This code consist of a 1) HTML form, 2) a display function on the HTML form and
3) a process to manage the form input.

Can you show me what I am doing wrong and or how to correct it ?

$field_unit = $fee1_unit[$index2];//assign field to array for function
check_unit_fiel d($field_unit);//funtion to validate user entered numbers or message sent


//insert statement goes here

}
?>

[/php]


I have added the code below to the process to get rid of
the errors but this creates another problem where the
for loop can't extract the data from the arrays.

[php]

//create array A
$fee_unit = array($fee_unit );
$fee_money = array($fee_mone y);


//create array B
$fee1_unit = array($fee1_uni t);
$fee1_money = array($fee1_mon ey);

I hope the following code statement is a type\

$all_array = array(fee_choice, fee_unit, fee_money, fee1_choice, fee1_unit, fee1_fee, fee2_choice, fee2_code, fee2_unit, fee2_describe, fee2_money, fee3_choice, fee3_code, fee3_unit, fee3_describe, fee3_money);
 

if not, what are you addressing here? Not php variables!

Have you printed (print_r($_POST ) the POST array to see what is the construction of e.g. $_POST['fee_unit'] ?

Hi Ron

Thanks for responding.

I altered the values assigned to $all_array used by the return starement.
This seems to be working and I have not received any error or warning messages yet.

Working change

[php]
$all_array = array($fee_choi ce, $fee_unit, $fee_money, $fee1_choice, $fee1_unit, $fee1_fee, $fee2_choice, $fee2_code, $fee2_unit, $fee2_describe, $fee2_money, $fee3_choice, $fee3_code, $fee3_unit, $fee3_describe, $fee3_money);

[/php]

I think this can be considered resolved, unless you think other wise.

Who marks the discussion as resolved?

[ronverdonk]

I will.
