PHP file upload into mysql - php

Question

I have created a form as follows. What I'm doing is
User is selecting a client from drop down list and uploading file. When he clicks on Add button the page will redirect to Confirm.php.
The Confirm.php will show whatever the user has given the input i.e, Client name and name of the file which he has uploaded.
In Confirm.php the user is submitting the form and it should add to the database, except file upload remaining fields are adding to the database. In database, file upload field is showing empty. Please somebody solve this problem.
And I'm not getting how to access path variable from Confirm.php into Add.php.
I'm new to the php. So any help will be appreciated.
Thank you.
Home.php
<form action="Confirm.php" method="post" enctype="multipart/form-data" novalidate>
<label> <span>Client</span>
<select class="required" name="client">
<?php
mysql_connect ("localhost","root","");
mysql_select_db ("eservice");
$select="eservice";
if (isset ($select)&&$select!="")
{
$select=$_POST ['NEW'];
}
?>
<?php
$list=mysql_query("select * from client");
while($row_list=mysql_fetch_assoc($list))
{
?>
<?php $ct = $row_list['cname'];?>
<option value="<?php echo $ct; ?>"<?php if($ct==$select){ echo "selected"; } ?> > <?php echo $ct; ?></option>
<?php } ?>
</select>
</label>
<label> <span>SRN</span>
<?php
$con=mysqli_connect("localhost","root","","eservice");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql="Select * from main";
if ($result=mysqli_query($con,$sql))
{
// Return the number of rows in result set
$rowcount=mysqli_num_rows($result);
$rowcount++;
// Free result set
mysqli_free_result($result);
}
mysqli_close($con);
?>
<input name="srn" type="text" id="srn" size="15" readonly="readonly" maxlength="40" value="<?php echo "$rowcount"; ?>"/>
</label>
</div>
<label>
<span>File upload</span>
<input type="file" name ="filename" required>
</label>
<button id='send' type='submit'>Add</button>
<button id='clear' type='reset'>Reset</button>
</form>
And this is my cofirmation page
Confirm.php
<form action="Add.php" method="post" enctype="multipart/form-data" novalidate>
<label> <span>Client</span>
<?php include_once('dbconn.php'); ?>
<input name="client" type="text" id="client" size="15" readonly="readonly" maxlength="40" value="<?php echo $_POST['client']; ?>"/>
</label>
<label>
<span>File upload</span>
<?php $path = '';
$folder = "Folder/";
if (is_uploaded_file($_FILES['filename']['tmp_name']))
{
if (move_uploaded_file($_FILES['filename']['tmp_name'], $folder.$_FILES['filename']['name']))
{
$path = $folder . $_FILES['filename']['name'];
}
else
{
$path = '';
};
}
else
{
$path = '';
}; ?>
<input name ="filename" readonly="readonly" value="<?php echo $_FILES['filename']['name']; ?>"/>
</label>
<button id='clear' type='reset'>Back</button>
<button id='send' type='submit'>Add</button>
</form>
dbconn.php
<?php
$username = "root";
$password = "";
$hostname = "localhost";
$dbhandle = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");
$selected = mysql_select_db("eservice",$dbhandle)
or die("Could not select newsite database");
?>
Here I'm adding the uploaded file into the phpmyadmin.
Add.php
<?php
include_once('dbconn.php');
session_start();
$_SESSION['example']='Session Created';
$client = $_POST['client']; // required
if($client !='')
{
$insQry = "Insert into `main` (client,upload) Values ('$client','$path')";
$insertQ = mysql_query($insQry);
if($insertQ!=''){
echo "<h2>Data inserted successfully...</h2>";
} else {
echo "<h2>Not added</h2>";
}
}
?>

Answer 1

Undefined Index means if that index is not set or empty...you have to check is it empty or not.
add condition in filename error
if ( $_FILES['filename']['error'] == 0 ){
///your uploading code
}
and for post veriable check it is isset or not, use ternary operator:-
$client =isset( $_POST['client'])?$_POST['client']:'';

Answer 2

Your confirm.php code should be
<form action="Add.php" method="post" enctype="multipart/form-data" novalidate>
<label> <span>Client</span>
<?php include_once('dbconn.php'); ?>
<input name="client" type="text" id="client" size="15" readonly="readonly" maxlength="40" value="<?php echo $_POST['client']; ?>"/>
</label>
<label>
<span>File upload</span>
<?php $path = '';
$folder = "Folder/";
if (is_uploaded_file($_FILES['filename']['tmp_name']))
{
if (move_uploaded_file($_FILES['filename']['tmp_name'], $folder.$_FILES['filename']['name']))
{
$path = $folder . $_FILES['filename']['name'];
}
else
{
$path = '';
};
}
else
{
$path = '';
}; ?>
<input name ="filename" readonly="readonly" value="<?php echo $_FILES['filename']['name']; ?>"/>
<input name ="path" type="hidden" value="<?php echo $path; ?>"/>
</label>
<button id='clear' type='reset'>Back</button>
<button id='send' type='submit'>Add</button>
</form>
You can get your hidden field value on add.php using $path = $_POST['path']
