Fetch MySQL table data with specific value - php

Question

I'm trying to edit the value and/or add more values to table options using PHP, here is a screen shot:
I started of with the following, now Im trying to see how I can pull the data that's associated with form_field_id, in this example is 5.
<?php
require_once("config/database.php");
$con = mysql_connect($config["db_server"],$config["db_user"],$config["db_pass"]);
mysql_select_db($config['db_name'], $con);
// get value of id that sent from address bar
$id=$_GET['form_field_id'];
// Retrieve data from database
$sql="SELECT * FROM options WHERE id='$form_field_id'";
$result=mysql_query($sql);
$rows=mysql_fetch_array($result);
?>
<form name="form1" method="post" action="updated_values.php">
<input name="name" class="form-control" type="text" id="name" value="<? echo $rows['value']; ?>">
<input name="name" class="form-control" type="text" id="name" value="<? echo $rows['value']; ?>">
<input name="name" class="form-control" type="text" id="name" value="<? echo $rows['value']; ?>">
<input name="name" class="form-control" type="text" id="name" value="<? echo $rows['value']; ?>">
<input name="name" class="form-control" type="text" id="name" value="<? echo $rows['value']; ?>">
<input name="name" class="form-control" type="text" id="name" value="<? echo $rows['value']; ?>">
<button type="submit" /> Update </button>
</form>
Here is the updated code I added after your suggestion:
<?php
require_once("config/database.php");
$con = mysql_connect($config["db_server"],$config["db_user"],$config["db_pass"]);
mysql_select_db($config['db_name'], $con);
// get value of id that sent from address bar
$id=$_GET['form_field_id'];
// Retrieve data from database
$sql="SELECT * FROM options WHERE id='$id'";
$result=mysql_query($sql);
$rows=mysql_fetch_array($result);
?>
<form name="form1" method="post" action="updated_values.php">
<?php
while($rows=mysql_fetch_array($result))
{
?>
<input name="name[]" class="form-control" type="text" id="name" value="<? echo $rows['value']; ?>">
<?php } ?>
<button type="submit" /> Update </button>
</form>

Answer 1

You have an error in your query, you are passing a variable thta you didn't assign so change first query as follow
$sql="SELECT * FROM options WHERE id='$id'";
//^here you used a wrong variable
You also need to loop throw your records to print all them, so change as follow
<form name="form1" method="post" action="updated_values.php">
<?php
while($rows=mysql_fetch_array($result))
{
?>
<input name="name[]" class="form-control" type="text" id="name[]" value="<? echo $rows['value']; ?>">
<?php } ?>
<button type="submit" /> Update </button>
</form>
Note that i also changed name of your input and i added [] so you will have an array of name input.
As side note i'd say your code is highly vulnerable to mysql injection and you should switch either to mysqli or PDO and use prepared statments to avoid any problems.

Your code looks right. You just need to change this:
$sql="SELECT * FROM options WHERE id='$form_field_id'";
to this:
$sql="SELECT * FROM options WHERE form_field_id='$id'";
All you had wrong was the variable and the column name, and to show the results you have to properly loop through all the rows you get.
