Question

我有以下代码来处理我的PHP表单：

$result1 = $db->query("SELECT `name` FROM staff_fields WHERE `".$_SESSION['logged_business']."` = 'Yes'")->fetchAll(PDO::FETCH_ASSOC);
$query = "UPDATE staff SET ";
foreach($result1 as $q){
    $query .= $q['name']."=:".$q['name'].", ";
}
$query = rtrim($query, ' ,')." WHERE id=:id";
$stmt = $db->prepare($query);
foreach($result1 as $col){
    $stmt->bindParam(':'.$col['name'], $_POST[$col['name']]);
}

$stmt->bindParam(':id', $_POST['id']);
if($stmt->execute())
    header('Location: staff.php?updated');
else
    echo "<center><h1>Error Updating Staff</h1></center>";

以下代码为自己的表单。

$stmt = $db->prepare("SELECT * FROM staff_fields WHERE ".$_SESSION['logged_business']."='Yes'");
$stmt->execute();
$result = $stmt->fetchAll(PDO::FETCH_ASSOC);
$stmt1 = $db->prepare("SELECT * FROM staff WHERE id=:id");
$stmt1->bindParam(':id', $_GET['id']);
$stmt1->execute();
while($row1 = $stmt1->fetchAll(PDO::FETCH_ASSOC)){
$table = "<form action='./edit_staff.php' method='post'>
            <table align='center'>";
    foreach($result as $res){
        $table .= 
                "
                    <tr>
                        <td>".$res['label']."</td>
                        <td>";

                        if($res['type'] == "text"){
                            $table .= "<input type='text' name='".$res['name']."' value='".$row1[0][$res['name']]."'/>";
                        }
                        if($res['type'] == "date"){
                            $table .= "<input type='date' name='".$res['name']."' value='";         
                            $date = new DateTime($row1[0][$res['name']]);
                            $table .= $date->format('Y-m-d')."'/>";
                        }
                        if($res['type'] == "yesno"){
                            $table .= "<select name='".$res['name']."' />";     
                            if($row1[0][$res['name']] == "Yes"){
                                    $table .= "<option value='Yes' selected>Yes</option>
                                                <option value='No'>No</option>";
                            }else{
                                $table .= "<option value='No' selected>No</option>
                                            <option value='Yes'>Yes</option>";
                            }   
                            $table .="</select>";
                        }

            $table .=  "</td>
                    </tr>
                ";
    }
    $table .="<tr><td><input type='hidden' number='id' value='".$row1[0]['id']."' /></td><td><input type='submit' name='btn' value='Add Staff' /></td></tr></table></form>";
    echo $table;
}

然而，尽管调试代码并调查它并不起作用。这是代码的第一部分，它不起作用（表单提交）。我尝试在update语句中使用debug params，但这就是我得到的：

SQL: [642] UPDATE staff SET first_name1459057776924=:first_name1459057776924, last_name1459057788088=:last_name1459057788088, job_title1459057796608=:job_title1459057796608, proof_of_age_on_file1459057805910=:proof_of_age_on_file1459057805910, date_of_birth1459057814082=:date_of_birth1459057814082, start_date1459057824504=:start_date1459057824504, signed_contract_in_place1459057835607=:signed_contract_in_place1459057835607, references_received1459057869650=:references_received1459057869650, payroll_informa Params: 11 Key: Name: [24] :first_name1459057776924 paramno=-1 name=[24] ":first_name1459057776924" is_param=1 param_type=2 Key: Name: [23] :last_name1459057788088 paramno=-1 name=[23] ":last_name1459057788088" is_param=1 param_type=2 Key: Name: [23] :job_title1459057796608 paramno=-1 name=[23] ":job_title1459057796608" is_param=1 param_type=2 Key: Name: [34] :proof_of_age_on_file1459057805910 paramno=-1 name=[34] ":proof_of_age_on_file1459057805910" is_param=1 param_type=2 Key: Name: [27] :date_of_birth1459057814082 paramno=-1 name=[27] ":date_of_birth1459057814082" is_param=1 param_type=2 Key: Name: [24] :start_date1459057824504 paramno=-1 name=[24] ":start_date1459057824504" is_param=1 param_type=2 Key: Name: [38] :signed_contract_in_place1459057835607 paramno=-1 name=[38] ":signed_contract_in_place1459057835607" is_param=1 param_type=2 Key: Name: [33] :references_received1459057869650 paramno=-1 name=[33] ":references_received1459057869650" is_param=1 param_type=2 Key: Name: [45] :payroll_information_given_to_ho1459057881692 paramno=-1 name=[45] ":payroll_information_given_to_ho1459057881692" is_param=1 param_type=2 Key: Name: [26] :leaving_date1459057889857 paramno=-1 name=[26] ":leaving_date1459057889857" is_param=1 param_type=2 Key: Name: [3] :id paramno=-1 name=[3] ":id" is_param=1 param_type=2

为什么这段代码不起作用？ staff_fields包含字段以及表单中使用的字段，因此我不知道为什么这不起作用。

我尝试通过my.ini启用IIS中的日志，但是我没有记录任何内容。

这不是重复!!!! $stmt->execute()返回TRUE，因为我被重定向到staff.php?updated！

我也设置了$db->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );，因此您所关联的内容无效。在急速行动之前阅读问题。

你可以替换：

foreach($result1 as $q){
$query .= $q['name']."=:".$q['name'].", ";
}

使用

foreach($result1 as $q){
$query .= $q['name']."='".$_POST[$q['name']]."', ";
}

您使用表单提交值但未捕获表单中发布的值。

希望这有效。

干杯

PHP PDO没有错误但没有工作
