I am currently trying to complete a project where the specifications are to use a search form to search through a packaging database. The database has lots of variables ranging from Sizes, names, types and meats. I need to create a search form where users can search using a number of different searches (such as searching for a lid tray that is 50 cm long).
I have spent all day trying to create some PHP code that can search for info within a test database I created. I have had numerous amounts of errors ranging from mysql_fetch_array errors, boolean errors and now currently my latest error is that my table doesn't seem to exist. Although i can enter data into it (html and php pages where I can enter data), I don't know what is causing this and I have started again a few times now.
Can anyone give me some idea or tips of what I am going to have to do currently? Here is just my small tests at the moment before I move onto the actual sites SQL database.
Creation of database:
<body>
<?php
$con = mysql_connect("localhost", "root", "");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
if (mysql_query("CREATE DATABASE db_test", $con))
{
echo "Database created";
}
else
{
echo "Error creating database: " . mysql_error();
}
mysql_select_db("db_test", $con);
$sql = "CREATE TABLE Liam
(
Code varchar (30),
Description varchar (30),
Category varchar (30),
CutSize varchar (30),
)";
mysql_query($sql, $con);
mysql_close($con);
?>
</body>
HTML search form page:
<body>
<form action="form.php" method="post">
Search: <input type="text" name="term" /><br />
<input type="submit" name="submit" value="Submit" />
</form>
</body>
The PHP code I am using to attempt to gather info from the database (I have rewritten this a few times, this code also displays the "table.liam doesn't exist")
<body>
<?php
$con = mysql_connect ("localhost", "root", "");
mysql_select_db ("db_test", $con);
if (!$con)
{
die ("Could not connect: " . mysql_error());
}
$sql = mysql_query("SELECT * FROM Liam WHERE Description LIKE '%term%'") or die
(mysql_error());
while ($row = mysql_fetch_array($sql)){
echo 'Primary key: ' .$row['PRIMARYKEY'];
echo '<br /> Code: ' .$row['Code'];
echo '<br /> Description: '.$row['Description'];
echo '<br /> Category: '.$row['Category'];
echo '<br /> Cut Size: '.$row['CutSize'];
}
mysql_close($con)
?>
</body>

try this out let me know what happens.
Form:
<form action="form.php" method="post">
Search: <input type="text" name="term" /><br />
<input type="submit" value="Submit" />
</form>
Form.php:
$term = mysql_real_escape_string($_REQUEST['term']);
$sql = "SELECT * FROM liam WHERE Description LIKE '%".$term."%'";
$r_query = mysql_query($sql);
while ($row = mysql_fetch_array($r_query)){
echo 'Primary key: ' .$row['PRIMARYKEY'];
echo '<br /> Code: ' .$row['Code'];
echo '<br /> Description: '.$row['Description'];
echo '<br /> Category: '.$row['Category'];
echo '<br /> Cut Size: '.$row['CutSize'];
}
Edit: Cleaned it up a little more.
Final Cut (my test file):
<?php
$db_hostname = 'localhost';
$db_username = 'demo';
$db_password = 'demo';
$db_database = 'demo';
// Database Connection String
$con = mysql_connect($db_hostname,$db_username,$db_password);
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db($db_database, $con);
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title></title>
</head>
<body>
<form action="" method="post">
Search: <input type="text" name="term" /><br />
<input type="submit" value="Submit" />
</form>
<?php
if (!empty($_REQUEST['term'])) {
$term = mysql_real_escape_string($_REQUEST['term']);
$sql = "SELECT * FROM liam WHERE Description LIKE '%".$term."%'";
$r_query = mysql_query($sql);
while ($row = mysql_fetch_array($r_query)){
echo 'Primary key: ' .$row['PRIMARYKEY'];
echo '<br /> Code: ' .$row['Code'];
echo '<br /> Description: '.$row['Description'];
echo '<br /> Category: '.$row['Category'];
echo '<br /> Cut Size: '.$row['CutSize'];
}
}
?>
</body>

You're getting errors 'table liam does not exist' because the table's name is Liam which is not the same as liam. MySQL table names are case sensitive.
