Compare $_POST array to new array

[davefootball123]

Hi all. I have an HTML Input array seen below. I am using a php script to get the checked values. I am using the foreach method to get the values of the input array. How would I compare the values of the input array from the html to an array in my php script? My current php script is shown below. As you can see the array has the values of the input array...as well as the corresponding text value that would be echoed by my script. How would I compare the input array that I used $_POST['calltotor'] to retrieve to the array seen in the php script to get the corresponding value.

Any help would be great. Thanks,

if ($_POST['warntype'] == 'TOR') {

foreach($_POST['calltotor'] as $toractions) {




        }
}

try

 

 

foreach($_POST['calltotor'] as $toractions)
{
  if(array_key_exists($toractions, $callstoaction))
    echo $callstoaction[$toractions] . "<br>";
}

In your foreach

if in_arrray ($toractions, $callstocation ) {do your stuff here;}

AyKay47 is right, you are POSTING keys not values.

I would have guessed that PHP would have a built in function to do an array_intersect using the values of one array against the indexes of another, but I don't see one. So, I see two options that would not require a foreach loop.

 

1. Use the POST array values to create an array using those as keys using array_fill_keys() and use that with array_intersect_key() to get the resulting array.

$selectedValuesAry = array_intersect_key($callstoaction, array_fill_keys($_POST['calltotor']));

 

2. To make things VERY simple you can just modify your checkboxes so you have ALL the information in the POST array. Use the keys from the $callstoaction array as the keys of the checkbox array and the values as the values:

 

<input type="checkbox" name="calltotor[defaulttor]" value="Default Tornado Warning"> Default Tornado Warning<br>
<input type="checkbox" name="calltotor[mobilehome]" value="Mobile Home"> Mobile Home<br>

 

The post value $_POST['calltotor'] will now have all the selected options and ther keys and values will be the same as the associated keys and values from the master array. You SHOULD be creating those checkboxes dynamically from the master array anyway, so this is by far the easiest and smartest option, in my opinion.
