[英]Display all rows and update all rows by a submit
I want to display all rows by a php query and update all by a submit button in sql. 我想通过php查询显示所有行,并通过sql中的提交按钮更新所有行。 I this way below a can display all row and update particular row by its own submit button.
我可以通过以下方式通过自己的提交按钮显示所有行并更新特定行。 But I want to update all by a single submit button.
但是我想通过一个提交按钮来全部更新。
So for do it, I thank, I want to loop for update. 为此,谢谢,我想循环进行更新。 But I cannot understand how to do it in this case.
但是在这种情况下,我不知道该怎么做。
Here is my code: 这是我的代码:
<?php
include_once('../db.php');
global $db;
$result = mysqli_query($dbh,"SELECT * FROM ppad");
if(!$result) {
die("Database query failed: " . mysqli_error());
}
while($row = mysqli_fetch_assoc($result)) {
$id=$row['id'];
$name=$row['name'];
$date=$row['date'];
$title=$row['title'];
$Detail=$row['Detail'];
echo '<form action="padSproccess.php" method="POST">
<table width="100%" border="1">
<tr>
<td width="10%">Date</td>
<td width="14%">Time</td>
<td width="20%">Name(url)</td>
<td width="30%">Detail</td>
</tr>
<tr>
<td width="10%"><input type="text" name="date" maxlength="2" value="'.$date.'"></td>
<td width="14%"><input type="text" name="title" maxlength="50" value="'.$title.'"></td>
<td width="20%"><input type="text" name="name" maxlength="50" value="'.$name.'"></td>
<td width="30%"><input type="text" name="Detail" maxlength="100" value="'.$Detail.'"></td>
<input type="hidden" name="id" value="'.$id.'">
</tr>
</table>
<input type="submit" name="submit" id="submit" value="Submit">
</form>';}
?>
padSproccess.php
include("../db.php");
global $db;
if(isset($_POST['submit'])){
$date = mysqli_real_escape_string($dbh,$_POST['date']);
$title = mysqli_real_escape_string($dbh,$_POST['title']);
$name = mysqli_real_escape_string($dbh,$_POST['name']);
$Detail = mysqli_real_escape_string($dbh,$_POST['Detail']);
$id = mysqli_real_escape_string($dbh,$_POST['id']);
// update data in mysql database
$update = mysqli_query($dbh,"UPDATE ppad SET date='$date', month='$month', name='$name', Detail='$Detail' WHERE id = '$id'");
// if successfully updated.
}
For this you need to update your code into 为此,您需要将代码更新为
<?php
include_once('../db.php');
global $db;
$result = mysqli_query($dbh,"SELECT * FROM ppad");
if(!$result) {
die("Database query failed: " . mysqli_error());
}?>
<form action="padSproccess.php" method="POST">
<table width="100%" border="1">
<tr>
<td width="10%">Date</td>
<td width="14%">Time</td>
<td width="20%">Name(url)</td>
<td width="30%">Detail</td>
</tr>
<?php
while($row = mysqli_fetch_assoc($result)) {
$id=$row['id'];
$name=$row['name'];
$date=$row['date'];
$title=$row['title'];
$Detail=$row['Detail'];
echo '<tr>
<td width="10%"><input type="text" name="date[]" maxlength="2" value="'.$date.'"></td>
<td width="14%"><input type="text" name="title[]" maxlength="50" value="'.$title.'"></td>
<td width="20%"><input type="text" name="name[]" maxlength="50" value="'.$name.'"></td>
<td width="30%"><input type="text" name="Detail[]" maxlength="100" value="'.$Detail.'"></td>
<input type="hidden" name="id[]" value="'.$id.'">
</tr>';
}?>
</table>
<input type="submit" name="submit" id="submit" value="Submit">
</form>
Now within your padSproccess.php
you'll receive an array of results within your variables which'll be updated using foreach
loop 现在,在
padSproccess.php
您将在变量中收到一系列结果,这些结果将使用foreach
循环进行更新
Try this. 尝试这个。 Of course for the database I've not started and it is possible errors.
当然对于数据库我还没有启动,并且可能会出现错误。
<?php
include_once('../db.php');
global $db;
$result = mysqli_query($dbh,"SELECT * FROM ppad");
if(!$result) {
die("Database query failed: " . mysqli_error());
}
?>
<form action="padSproccess.php" method="POST">
<?php
while($row = mysqli_fetch_assoc($result)) {
$id=$row['id'];
$name=$row['name'];
$date=$row['date'];
$title=$row['title'];
$Detail=$row['Detail'];
echo '
<table width="100%" border="1">
<tr>
<td width="10%">Date</td>
<td width="14%">Time</td>
<td width="20%">Name(url)</td>
<td width="30%">Detail</td>
</tr>
<tr>
<td width="10%"><input type="text" name="ar['.$id.'][date]" maxlength="2" value="'.$date.'"></td>
<td width="14%"><input type="text" name="ar['.$id.'][title]" maxlength="50" value="'.$title.'"></td>
<td width="20%"><input type="text" name="ar['.$id.'][name]" maxlength="50" value="'.$name.'"></td>
<td width="30%"><input type="text" name="ar['.$id.'][Detail]" maxlength="100" value="'.$Detail.'"></td>
</tr>
</table>
';}
?>
<input type="submit" name="submit" id="submit" value="Submit">
</form>
<?php
include("../db.php");
global $db;
if(isset($_POST['submit'])){
foreach($_POST['ar'] as $id=>$dat){
$date = mysqli_real_escape_string($dbh,$dat['date']);
$title = mysqli_real_escape_string($dbh,$dat['title']);
$name = mysqli_real_escape_string($dbh,$dat['name']);
$Detail = mysqli_real_escape_string($dbh,$dat['Detail']);
$id = mysqli_real_escape_string($dbh,$id]);
// update data in mysql database
$update = mysqli_query($dbh,"UPDATE ppad SET date='$date', month='$month', name='$name', Detail='$Detail' WHERE id = '$id'");
}
// if successfully updated.
}
?>
What you need to do first is have an overall form, not a form for each (unless you want to throw in javascript to fire off ajax calls). 您首先需要做的是拥有一个整体表单,而不是每个表单都有一个表单(除非您想使用JavaScript来触发Ajax调用)。 So what you'll need to do is make sure each row can be associated with a specific id:
因此,您需要做的是确保每一行都可以与特定的ID相关联:
<?php
include_once '../db.php';
$result = mysqli_query($dbh, "SELECT * FROM ppad");
if(!$result) {
die("Database query failed: " . mysqli_error());
}
?>
<form action="padSproccess.php" method="POST">
<table width="100%" border="1">
<thead>
<tr>
<td width="10%">Date</td>
<td width="14%">Time</td>
<td width="20%">Name(url)</td>
<td width="30%">Detail</td>
</tr>
</thead>
<tbody>
<?php
while($row = mysqli_fetch_assoc($result)) {
$id = $row['id'];
$name = $row['name'];
$date = $row['date'];
$title = $row['title'];
$Detail = $row['Detail'];
echo '
<tr>
<td width="10%"><input type="text" name="date[' . $id . ']" maxlength="2" value="'.$date.'"></td>
<td width="14%"><input type="text" name="title[' . $id . ']" maxlength="50" value="'.$title.'"></td>
<td width="20%"><input type="text" name="name[' . $id . ']" maxlength="50" value="'.$name.'"></td>
<td width="30%"><input type="text" name="Detail[' . $id . ']" maxlength="100" value="'.$Detail.'"></td>
</tr>
';
}
?>
</tbody>
</table>
<input type="submit" name="submit" id="submit" value="Submit">
</form>
Then in padSproccess.php
you'll receive an array of names
, dates
, titles
and Details
, each one keyed by the ID
of the row. 然后在
padSproccess.php
您将收到一个由names
, dates
, titles
和Details
的数组,每个数组均由行的ID
键入。 So that'll change to something like this: 因此,它将变为如下所示:
<?php
include "../db.php";
if(isset($_POST['submit'])){
$ids = array_keys($_POST['name']);
foreach ($ids as $id) {
$date = mysqli_real_escape_string($dbh,$_POST['date'][$id]);
$title = mysqli_real_escape_string($dbh,$_POST['title'][$id]);
$name = mysqli_real_escape_string($dbh,$_POST['name'][$id]);
$Detail = mysqli_real_escape_string($dbh,$_POST['Detail'][$id]);
$id = mysqli_real_escape_string($id);
// update data in mysql database
$update = mysqli_query($dbh,"UPDATE ppad SET date='$date', month='$month', name='$name', Detail='$Detail' WHERE id = '$id'");
}
// if successfully updated.
}
