Question

我想问一下处理这些代码的有效方法是什么。即时检查表单中的更改，如果有更改，则存储到DB。有没有办法将4 if语句转换为一个。感谢

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(); 
}

Answer 1

将输入字段作为数组返回，然后循环这些值，然后以这种方式，您的代码将更短，更简单，更动态。：）

Answer 2

在表格上：

<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">

提交和处理：

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

这样的事情。：）
