Basic PHP/MySQL INSERT INTO Multiple Tables from Forms - mysql

Question

I am trying to make a simple PHP form submission and insert some data to MySQL, my tables are:
category: id, category_name
table1: category_id(FK), title,description
table2: table1_id(FK), filetype, filesize, filedate, filename
Form: Date, Title, description, category(drop down), upload file (get the file info like type, ext, size, filename)
Here is the code:
Form:
<strong>Fill up the form:</strong><br /><br>
<form enctype="multipart/form-data" action="upfileone.php" method="POST">
Date: <?php echo date("d-M-Y") ?>
<p>Title:
<input type="text" name="title" value="<?php echo $sel_filepage['file_title']; ?>" id="file_title" />
</p>
<p>Description:<br>
<textarea name="description" rows="4" cols="24">
<?php echo $sel_filepage['content']; ?></textarea>
</p>
Category:
<select name="select_cat">
<?php $cat_set = get_all_categs();
while($category = mysql_fetch_array($cat_set)){
$catname = $category['cat_name'];
echo '<option value="'.$catname.'">'.$catname.'</option>';
}
?>
</select>
<br><br>
<label for="file">Choose File to Upload:</label>
<input type="file" name="upfile" id="upfile" > <br /><br />
<input type="hidden" name="MAX_FILE_SIZE" value="1000000" />
<input type="hidden" name="filepage" value="<?php echo $_GET['filepage']?>">
<input type="submit" name="upload" value="Add" class="pure-button pure-button-success">
Cancel
</form> <!-- END FORM -->
Action file:
<?php
require_once("includes/functions.php");
// directory to be saved
$target = "server/php/files/";
$target = $target . basename($_FILES['upfile']['name']);
// gets info from FORM
$currentDate = date("Y-m-d");
$file_title = $_POST['title'];
$content = $_POST['description'];
$category = $_POST['select_cat'];
$upfile = ($_FILES['upfile']['name']);
// connects to db
$con = mysqli_connect("localhost", "root", "password", "database");
if(mysqli_connect_errno())
{
echo "error connection" . mysqli_connect_error();
}
// insert to database
$sql = "INSERT INTO filepages (category_id,file_title,content)
VALUES ('$category','$file_title','$content')";
/*$sql2 = "BEGIN
INSERT INTO filepages (category_id, file_title, content)
VALUES ('$category','$file_title','$content')
INSERT INTO fileserv (file_date)
VALUES ($currentDate)
COMMIT";*/
if(!mysqli_query($con, $sql))
{
die('Error ' . mysqli_error());
}
echo "1 File Added <br>";
if (file_exists("server/php/files/" . $_FILES["upfile"]["name"]))
{
echo $_FILES["upfile"]["name"] . " already exists. ";
}
else
{
insertFile( $_POST['filepage'],
$_FILES["upfile"]["type"],
($_FILES["upfile"]["size"] / 1024),
$_FILES["upfile"]["name"]);
move_uploaded_file($_FILES["upfile"]["tmp_name"],"server/php/files/" . $_FILES["upfile"]["name"]);
echo "The FILE " . basename($_FILES['upfile']['name']) . " has been uploaded.<br>";
echo "Stored in: " . "server/php/files/" . $_FILES["upfile"]["name"] . "<br>";
echo "Upload: " . $_FILES["upfile"]["name"] . "<br>";
echo "Type: " . $_FILES["upfile"]["type"] . "<br>";
echo "Size: " . ($_FILES["upfile"]["size"] / 1024) . " kB<br>";
echo "Temp file: " . $_FILES["upfile"]["tmp_name"] . "<br>";
}
?>
It does insert to both tables, now my main problem is how to get the ID from drop down menu of category and insert to Filepages.category_id.
How can I get the Filepages.ID data and insert it to Fileserve?

Answer 1

So you want the ID of the inserted row.
You can simply use the following php function http://www.php.net/manual/en/mysqli.insert-id.php
This question should nonetheless be moved to stackoverflow
