Question

I would like to ask what is the efficient way to deal with these code. im checking changes in the form and if there are changes it store to DB. is there a way to convert 4 if statement into one. thanks

if ($_REQUEST['hidden_value_of_input_box1'] !== $newvalueofinputbox1) {    

    $data = "Input Box 1 has been changed";

    $name = $name;   
    $date = $datenow;    
    $stm = $dbh->prepare("INSERT INTO audit SET name=:name, datenow=:datenow, data=:data");     
    $stm->bindParam(':name', $name);   $stm->bindParam(':value', $value);   
    $stm->execute(); 
}  

if ($_REQUEST['hidden_value_of_input_box2'] !== $newvalueofinputbox2) {    

    $data = "Input Box 2 has been changed";

    $name = $name;   
    $date = $datenow;    
    $stm = $dbh->prepare("INSERT INTO audit SET name=:name, datenow=:datenow, data=:data");     
    $stm->bindParam(':name', $name);   $stm->bindParam(':value', $value);   $stm->execute(); 
}  

if ($_REQUEST['hidden_value_of_dropdown1'] !== $newvalueofdropdown1) {    

    $data = "Drop Down 1 has been changed";    

    $name = $name;   
    $date = $datenow;    
    $stm = $dbh->prepare("INSERT INTO audit SET name=:name, datenow=:datenow, data=:data");     
    $stm->bindParam(':name', $name);   $stm->bindParam(':value', $value);   $stm->execute(); 
}  

if ($_REQUEST['hidden_value_of_dropdown2'] !== $newvalueofdropdown2) {    

    $data = "Drop Down 2 has been changed";   

    $name = $name;   
    $date = $datenow;    
    $stm = $dbh->prepare("INSERT INTO audit SET name=:name, datenow=:datenow, data=:data");     
    $stm->bindParam(':name', $name);   
    $stm->bindParam(':value', $value);   
    $stm->execute(); 
}

on the form:

<input name="hidden_value_of_input_box[]" type="hidden" value="anyvalue">
<input name="hidden_value_of_input_box[]" type="hidden" value="anyvalue">
<input name="hidden_value_of_input_box[]" type="hidden" value="anyvalue">

on the submition and processing:

<?php
foreach($_POST["hidden_value_of_input_box"] as $value){
echo $value;
}
?>

something like that. 🙂
