I have a problem with my PHP code saying that "Notice: Undefined index" I am sure its very simple, since I am a beginner i am not getting well what is wrong exactly so please help me.
Here's the code
<?php require_once('../Connections/itemconn.php'); ?> <?php $id=$_GET['id']; $query=mysql_query("select * from manuf where id='$id' ")or die(mysql_error()); $row=mysql_fetch_array($query); ?> <form action="updateprice.php" method="post" enctype="multipart/form-data"> <table align="center"> <tr> <td> <label><strong>Item Name</strong></label></td> <td> <label> <?php echo $row['itemname']; ?></label><input type="hidden" name="id" value="<?php echo $id; ?> " /> <br /></td> </tr> <tr> <td><label><strong>Unit price </strong></label></td> <td> <input type="text" name="pass" value="<?php echo $row['unitprice']; ?> " /><br /></td> </tr> <tr> <td> <input type="reset" name="Reset" value="CANCEL" /> <br></td> <td> <input type="submit" name="Submit2" value="Update" /> </td> </tr> </table> </form> </body> </html> 3 Answers
You are not getting value of $id=$_GET['id'];
And you are using it (before it gets initialised).
Use php's in built isset() function to check whether the variable is defied or not.
So, please update the line to:
$id = isset($_GET['id']) ? $_GET['id'] : ''; if you are getting id from url try
$id = (isset($_GET['id']) ? $_GET['id'] : ''); if getting from form you need to use POST method cause your form has method="post"
$id = (isset($_POST['id']) ? $_POST['id'] : ''); For php notices use isset() or empty() to check values exist or not or initialize variable first with blank or a value
$id= ''; Simply add this
$id = ''; if( isset( $_GET['id'])) { $id = $_GET['id']; }
