[SOLVED] PHP Array

[drinksbreak]

Hi Guys

 

Maybe you can help. Im working with an array in my php script and need to pass the entire array through a form. Here is the script. Take a look and tell me if you can see my mistake.

 

I create a dynamic entry screen that has multiple values that I would like to update and want to place them all into an array to update them. At the mo no values are being posted at all.

EG:

 

Entry screen

 

****START FROM*****

 

Update (product1) [  VALUE ]

Update (product2) [ VALUE ]

Update (product2) [ VALUE ]

 

Update All

****** END FORM **************

 

 

Thanks in advance

 

 

*****POST SCRIPT********************

 

$trans = array();

            for($i = 0; $i < $rowz ; $i++)

            {         

                                                $trans[] = $_POST['max_value[]'];

            }

                                                foreach($trans as $view)

                                                {

                                                            echo "LETS TRY AGAIN : $view <br>";

                                                }

 

************UPDATE SCRIPT******************

 

Have not written this yet until I see that all the correct values are being passed through the array.

 

***********************OUTSIDE FORM****************************************

 

$max_value = array();

**********************INSIDE FORM************************

for ($i=0; $i <$num_results; $i++)

{

<input type="text" name="<? echo "max_value[$i]"; ?>" value="<? echo "$cur_markup"; ?>">

}

 

 

Thank You

your $_POST array notation is off - when you name an input as an array, it actually forms an array in the $_POST data:

 

$_POST['max_value'][0] => the value from the first input named 'max_value[]'

 

i haven't analysed your whole block of code, but i trust that's where the issue lies.  just run a foreach() on $_POST['max_value'] to grab all the values entered.

You can try this:

 

**********************INSIDE FORM************************

for ($i=0; $i <$num_results; $i++)

{

<input type="text" name="array_values[<? echo "$max_value[$i]"; ?>]" value="<? echo "$cur_markup"; ?>">

}

 

so that the name parameter will be "array_values[0]", "array_values[1]", "array_values[2]", ens.

Where for example ids is:

  0    => Hardware

  1    => Software

  2    => Consumables

 

Let's say the values you input for the form is:

  0    => 5

  1    => 6

  2    => 8

 

Then when you get the the Post value it will be "$_POST['array_values']" which will already be an array, so if you want to set it equal to another empty value just say:

  $the_array =  $_POST['array_values'];

 

When go through the array with:

  foreach ($the_array as $key => $value) {

      echo "$key => $value <br>";

  }

 

You'll get the result of:

 

  0    => 5

  1    => 6

  2    => 8
