Matt_C Posted August 21, 2013 Share Posted August 21, 2013 Please ignore the fact i have a form etc in my class and it submits to the class, what i am stuck on is finding the value from my associative array with the key that passed in the $_POST request. I have looked in the php manual and looked at other fixes people have posted online but something is not right. Easy fix for a seasoned developer i am sure, please help if you have a min. <?php class World { public $world_countries = array( "GB" => "United Kingdom", "US" => "United States", "AF" =>

Psycho Posted August 21, 2013 Share Posted August 21, 2013 Assuming all of your HTML markup is valid: Â $selectedCountryName = $world_countries[$_POST['country']]; Quote Link to comment Share on other sites More sharing options...
Matt_C Posted August 21, 2013 Author Share Posted August 21, 2013 Hi Psycho, Â Thank you for getting back to me. Â Yes, it is all valid. I have no problem assigning it to a variable, i just can't figure out how to search the $world_countries array using $selectedCountryName and return the value for use/output. Because $_POST value will be the key (abbreviation)...and i want to out put the value (Country name) found in the $world_countries array.

Psycho Posted August 22, 2013 Share Posted August 22, 2013 Hi Psycho,  Thank you for getting back to me.  Yes, it is all valid. I have no problem assigning it to a variable, i just can't figure out how to search the $world_countries array using $selectedCountryName and return the value for use/output. Because $_POST value will be the key (abbreviation)...and i want to out put the value (Country name) found in the $world_countries array.  Matt, I provided the exact code you need! The select field will post the "key" of the selected value in the variable $_POST['country']. So, just use that as the key in the array $world_countries to get the selected value as I posted previously. I thought I made the variables names such that this would be clear. $selectedCountryName = $world_countries[$_POST['country']];  Now, one additional step you could take would be to validate the value in the returned POST data  //Check if the POSTed value is a key in the countries array if(array_key_exist($_POST['country'], $world_countries)) {    //Set the selected value (i.e. country name)    $selectedCountryName = $world_countries[$_POST['country']]; } else {    //Posted value is not a key in the array - create error condition } Quote Link to comment Share on other sites More sharing options...
