Displaying Images, and SessionStart();
Posted: Tue Oct 27, 2009 6:38 am
Okay. First up, I'm new. Both to this forum, and to PHP/MySQL. Well, relatively new, anyways. Yaaay.
I have two questions. For both, I've looked around, and can't seem to find anything that explains it in clear terms.
1: I have a MySQL database with a list of products. These products have associated images (of which the links are stored in the database). How do I use these links to display the image when a user enters a search term?
The current PHP Search code is the following:
2: I can't seem to get my sessionStart(); to work. The error that I recieve is "Fatal error: Call to undefined function sessionstart() in C:\xampp\htdocs\BazaarCeramics-Final\includes\session.php on line 2" ... Session Support is enabled on Apache... so what do I do?

The current PHP Search code is the following:
Code: Select all
<?php
// Get the search variable from URL
$var = @$_GET['q'] ;
$trimmed = trim($var); //trim whitespace from the stored variable
// rows to return
$limit=10;
// check for an empty string and display a message.
if ($trimmed == "")
{
echo "<p>Please enter a viable search parameter...</p>";
return("No search parameters entered");
}
// check for a search parameter
if (!isset($var))
{
echo "<p>We dont seem to have a search parameter!</p>";
exit;
}
//connect to your database ** EDIT REQUIRED HERE **
mysql_connect("localhost","root","rootadmin"); //(host, username, password)
//specify database ** EDIT REQUIRED HERE **
mysql_select_db("jlcbazaarceramics") or die("Unable to select database"); //select which database we're using
// Build SQL Query
$query = "select productName,productDesc,productPrice,productImage from products where productName like \"%$trimmed%\"
order by productName"; // EDIT HERE and specify your table and field names for the SQL query
$numresults=mysql_query($query);
$numrows=mysql_num_rows($numresults);
// If we have no results, offer a google search as an alternative
if ($numrows == 0)
{
echo "<h4>Results</h4><br />";
echo "<p>Sorry, your search: "" . $trimmed . "" returned zero results</p>";
// google
echo "<p><a href=\"http://www.google.com/search?q="
. $trimmed . "\" target=\"_blank\" title=\"Look up
" . $trimmed . " on Google\">Click here</a> to try the
search on google</p>";
}
// next determine if s has been passed to script, if not use 0
if (empty($s)) {
$s=0;
}
// get results
$query .= " limit $s,$limit";
$result = mysql_query($query) or die("Couldn't execute query");
// display what the person searched for
echo "<p>You searched for: "" . $var . ""</p>";
// begin to show results set
echo "Results<br />";
$count = 1 + $s ;
// now you can display the results returned
while ($row= mysql_fetch_array($result)) {
echo ("<table border=\"1px\" width=\"100%\">");
echo ("<tr><td rowspan=4>");
$img = $row["productImage"];
echo ("<img src=\"$img\" />");
echo ("</td></tr>");

// next we need to do the links to other results
if ($s>=1) { // bypass PREV link if s is 0
$prevs=($s-$limit);
print " <a href=\"$PHP_SELF?s=$prevs&q=$var\"><<
Prev 10</a>  ";
}
// calculate number of pages needing links
$pages=intval($numrows/$limit);
// $pages now contains int of pages needed unless there is a remainder from division
if ($numrows%$limit) {
// has remainder so add one page
$pages++;
}
// check to see if last page
if (!((($s+$limit)/$limit)==$pages) && $pages!=1) {
// not last page so give NEXT link
$news=$s+$limit;
echo " <a href=\"$PHP_SELF?s=$news&q=$var\">Next 10 >></a>";
}
$a = $s + ($limit) ;
if ($a > $numrows) { $a = $numrows ; }
