I have few types of search criteria and i'm trying to mke different queries depending from url and post data
here is the examle code
Code:
if($_SERVER['REQUEST_METHOD'] == 'POST')
{
$sql = "SELECT
Object.ID,
Object.NasPunkt,
Object.Area,
Road.Value AS Road,
District.Value AS District
FROM
Object
LEFT OUTER JOIN
Road
ON Road.ID = Object.RoadID
LEFT OUTER JOIN
District
ON District.ID = Object.DistrictID
WHERE
1=1
";
echo "<h1>1</h1>";
}
elseif ($uri1 == 'acatalog')
{
$sql = "SELECT
Object.ID,
Object.NasPunkt,
Object.Area,
Road.Value AS Road,
District.Value AS District
FROM
Object
LEFT OUTER JOIN
Road
ON Road.ID = Object.RoadID
LEFT OUTER JOIN
District
ON District.ID = Object.DistrictID
ORDER BY ID DESC
";
echo "<h1>2</h1>";
}
elseif($uri1 == 'letter')
{
$letter = urldecode($uri2);
$sql = "SELECT
Object.ID,
Object.NasPunkt,
Object.Area,
Road.Value AS Road,
District.Value AS District
FROM
Object
LEFT OUTER JOIN
Road
ON Road.ID = Object.RoadID
LEFT OUTER JOIN
District
ON District.ID = Object.DistrictID
WHERE LOWER(Object.NasPunkt) LIKE '$letter%'
ORDER BY ID DESC
";
echo "<h1>3</h1>";
}
if(!empty($sql))
{
$this->session->set_userdata('equery', $sql);
}
else
{
$sql = $this->session->userdata('equery');
}
everything works fine except case with post. Session data is saved, and after I go on other page session variable becomes empty.
What may be a reason?
