Saving the selected rows by checkbox to database in php - php

Question

I have a query to display all the records of the ebooks table from the database.
I displayed it in a table with a checkbox from the first column.
I'm trying to save the rows from the selected checkbox in the table width the Name of School but I don't have any idea.
I'm just a beginner in php, any help is appreciated. Here is my codes:
HTML codes:
$result1 = mysql_query("SELECT * FROM school GROUP BY SCHOOL_NAME");
while($row1=mysql_fetch_array($result1)) {
?>
<option><?php echo $row1['SCHOOL_NAME'];?></option>
<?php } ?>
</select>
<table class="table table-striped table-hover table-bordered datatable">
<thead style="background: #a83535; color: black;">
<tr>
<th style="width: 50px;"></th>
<th style="color: #3b3b3b;">Ebook Title</th>
<th style="color: #3b3b3b;">Category</th>
<th style="color: #3b3b3b;">File Name</th>
</tr>
</thead>
<tbody>
<?php
$result = mysql_query("SELECT * from ebooks ORDER BY EBOOK_TITLE");
$count = mysql_num_rows($result);
while($row=mysql_fetch_array($result)) {
?>
<tr>
<td>
<center><input type="checkbox" name="check[]" ></center>
</td>
<td><input type="" name="ebookname[]" value="<?php echo $row['EBOOK_TITLE'];?>"></label></td>
<td><input type="" name="ebookcategory[]" value="<?php echo $row['EBOOK_CATEGORY'];?>"></label></td>
<td><input type="label" name="ebookfilename[]" value="<?php echo $row['EBOOK_FILENAME'];?>"></label></td>
</tr>
<?php } //end of while loop ?>
</tbody>
</table>
<button type="submit" class="btn btn-hg btn-primary" name="AddEbooks">Submit</button>
I want to save the rows selected by the checkbox to database:
Table: school_management
Columns: ID_NUMBER, SCHOOL, EBOOK, FILE_NAME, DATE_ASSIGN
Values (from the HTML table to database): ('','$school_ebook','$ebookname','$ebookfilename','')
Here is the screenshot:

Answer 1

First, you will need to assign an ID number to the checkboxes so that you can differentiate each record. Using the ID_NUMBER would be ideal here. In your current script where you are displaying the checkbox, your line that reads this:
<center><input type="checkbox" name="check[]" ></center>
Should include the ID_NUMBER like this in the name. Additionally, a value should be assigned to the checkbox so we can verify later.
<center><input type="checkbox" name="check[<?php echo $row['ID_NUMBER'];?>]" value="1"></center>
Now you can go ahead and set up something that gets triggered when your form is submitted. You can essentially loop through each record and check it against the "check[ID_NUMBER]" checkbox to see if the value is 1. If the value is 1 then the record had been checked to save and you can then carry on saving the record.
How you want to handle the form is up to you - you could do AJAX to avoid reloading the entire page or you could do a simple form action="page_name_here.php" and handle the submission there. If you go about doing a simple form post without AJAX, it could be something like this -
Current page form tag:
<form name="" action="page_name_here.php" method="POST">
If you want to use the school_ebook var you need to assign the select options for the school_ebook a value:
<option value="<?php echo $row1['SCHOOL_NAME']'?>">
page_name_here.php:
<?php
/* Get the school name */
$school_ebook=$_POST["school_ebook"];
/* Query your books DB to get the records */
$result=mysql_query("SELECT * from ebooks ORDER BY EBOOK_TITLE");
$count=mysql_num_rows($result);
while($row=mysql_fetch_array($result)) {
$bookID=$row['ID_NUMBER'];
/* Get the Book ID and now we have to fetch from $_POST the value from the form */
if (array_key_exists($bookID, $_POST["check"])) {
$ischecked=$_POST["check"][$bookID];
/* See if this has a value of 1. If it does, it means it has been checked */
if ($ischecked==1) {
/* It is checked, so now in this area you can finish the code to retrieve the data from the row and save it however you like */
}
}
}
?>
Once completed with your inserts, etc., it should accomplish what you need.
