我通过ajax调用将表单数据发送到php脚本。我在ajax和php脚本中序列化数据,我想循环遍历该数据以提取值。 这是我的ajax电话
$("#submitAttendance").click(function(){
var data = $('form#attendanceForm').serialize();
$.ajax({
url: 'save-attendance.php',
method: 'post',
data: {formData: data},
success: function(data){
console.log(data);
alert(data);
}
});
});
和{我正在做的attendance.php
print_r(($_POST['formData']));//prints the entire serialize data
当我这样做时
parse_str($_POST['formData'], $searcharray);
print_r(($searcharray));//prints only last user and all radio buttons
我想提取值,以便将其保存在db中。 这是我的表格
<form action="" id="attendanceForm">
<?php
if(mysqli_num_rows($result)>0){
while($row = $result->fetch_assoc()){ ?>
<tr>
<input type="hidden" value="<?php echo($row['id']);?>">
<td><input type="text" name="name" value="<?php echo $row['fullname'];?>" readonly></td>
<td><input type="text" name="email" value="<?php echo $row['email'];?>" readonly</td>
<td><input type="text" name="class" value="<?php echo $row['class'];?>" readonly</td>
<td><input type="radio" value="present" name="<?php echo($row['id']); ?>" checked></td>
<td><input type="radio" value="absent" name="<?php echo($row['id']); ?>"></td>
</tr>
<?php }
}
?>
<input id="submitAttendance" type="button" class="btn btn-success" value="Submit Attendance" name="submitAttendance">
</form>

你需要重命名你的项目以便能够发布数组(即称之为“what”+“[]”并在PHP中循环它们),例如:
<强> HTML:强>
<form action="" id="attendanceForm">
<?php
if(mysqli_num_rows($result)>0){
while($row = $result->fetch_assoc()){ ?>
<tr>
<input type="hidden" value="<?php echo($row['id']);?>">
<td><input type="text" name="name[]" value="<?php echo $row['fullname'];?>" readonly></td>
<td><input type="text" name="email[]" value="<?php echo $row['email'];?>" readonly</td>
<td><input type="text" name="class[]" value="<?php echo $row['class'];?>" readonly</td>
<td><input type="radio" value="present" name="<?php echo($row['id']); ?>" checked></td>
<td><input type="radio" value="absent" name="<?php echo($row['id']); ?>"></td>
</tr>
<?php }
}
?>
<input id="submitAttendance" type="button" class="btn btn-success" value="Submit Attendance" name="submitAttendance">
</form>
稍后在PHP中:
foreach ($_POST["formData"]["name"] as $name)
echo "Wow, $name is a really pretty name!";
此外,我不确定present
和absent
是什么意思以及为什么它们应该具有相同的名称(id)。您已经将id作为隐藏字段发布,为什么要将其作为两次?一个覆盖另一个(因为名称必须是唯一的)。

除了@Jan回答之外,我做了以下操作来获取完整的数据并循环遍历
解析传入的数据
parse_str($_POST['formData'], $searcharray);
然后遍历数组
for ($i = 0 ; $i <= sizeof($searcharray) ; $i++){
$name = $searcharray['name'][$i];
$email= $searcharray['email'][$i];
$class = $searcharray['class'][$i];
$present= ($searcharray['present'][$i]);
}
我的表单代码是
<form action="" id="attendanceForm">
<?php
if(mysqli_num_rows($result)>0){
$i=0;
while($row = $result->fetch_assoc()){
?>
<tr>
<input type="hidden" value="<?php echo($row['id']);?>">
<td><input type="text" name="name[]" value="<?php echo $row['fullname'];?>" readonly></td>
<td><input type="text" name="email[]" value="<?php echo $row['email'];?>" readonly</td>
<td><input type="text" name="class[]" value="<?php echo $row['class'];?>" readonly</td>
<td><input type="radio" value="present" name="present[<?php echo $i; ?>]" checked></td>
<td><input type="radio" value="absent" name="present[<?php echo $i; ?>]"></td>
</tr>
<?php $i++;
}
}
?>
<input id="submitAttendance" type="button" class="btn btn-success" value="Submit Attendance" name="submitAttendance">
</form>
