Query not returning all rows.

Recommended Posts

 Hello, my code below seems to work great when you enter a value into the input however it does not return all values when the input is empty. It shows rows 1-5 and 79-95 does anyone know how this is happening?

Thank you !

<div id="main">
<form method="post" action="">
<div id="search_query">
Keyword: <input type="text" name="brand">
<input type="submit" name="submit" value="submit">
</div>
</form>
<div id="main_container">
<?php
$db_con = mysql_connect('localhost', 'hwsuser', 'password');
if (!$db_con) {
    die('Could not connect: ' . mysql_error());
}
mysql_select_db('hws', $db_con);
if(!isset($_POST['submit']))
{
$sql = sprintf("SELECT * FROM hws");
$result = mysql_query($sql);
echo "<table>";
echo "<tr>";

It might couse of your condition.

$sql = sprintf("SELECT * FROM units WHERE Brand LIKE'$brand' OR Model LIKE'$brand' OR Capacity LIKE'$brand' OR Type LIKE'$brand'");

try it into "=="

$sql = sprintf("SELECT * FROM units WHERE Brand = '$brand' OR Model = '$model' OR Capacity = '$capacity' OR Type = '$type'");

Are the records that appear the ones that have an empty string value in one or more of those four columns?

 

Use the wildcard character "%" with LIKE. That way if $brand is empty then all values are matched.

$sql = "SELECT * FROM units WHERE Brand LIKE '%$brand%' OR Model LIKE '%$brand%' OR Capacity LIKE '%$brand%' OR Type LIKE '%$brand%'";

The 'like' query can have the possibility of returning more matches, especially if the argument it is given has the proper wildcards in it. '%PHP%', for instance, will match 'PHPFREAKS' and 'PHP', but as a literal it will not match anything that doesn't have the percent signs in those specific spots. In else part you may have records in DB with exact match.
