Display all rows and update all rows by a submit - php

Question

I want to display all rows by a php query and update all by a submit button in sql. I this way below a can display all row and update particular row by its own submit button. But I want to update all by a single submit button.
So for do it, I thank, I want to loop for update. But I cannot understand how to do it in this case.
Here is my code:
<?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
<?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

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). So what you'll need to do is make sure each row can be associated with a specific id:
<?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. So that'll change to something like this:
<?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.
}

Try this. Of course for the database I've not started and it is possible errors.
<?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.
}
?>
