hi fellas. first, just wanted to say what a great forum this is. well am a newbie to this whole php/mysql web development. am working on a project for uni and i have a very simple question and would like your help. Don't let the length of my post scare u, its nothing.
I used the search script which was posted in this topic:
http://www.designplace.org/forum/viewtopic.php?t=50
Am trying to search by name. I used the following sql statement:
$query = "select * from contacts where name like \"%$trimmed%\"
Now that works fine. The thing is that if i enter a single letter (not a string starting letter), it would still yield results.
For example i have the following data in the database:
Name Number
John 45
Jason 98
Katie 34
If i put only the letter o , it will give me back 2 results being john and jason although they dont start with an o.
What i would like to do is allow the script to search for partial or full matching results. For example, if i enter ka or k or katie, i want it to give me back katie.
Am not sure how to do that?
Can you please help me. That would be greatly appreciated.
Here is the script:
<HTML>
<BODY>
<?
// 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 search...</p>";
exit;
}
// check for a search parameter
if (!isset($var))
{
echo "<p>We dont seem to have a search parameter!</p>";
exit;
}
mysql_connect("localhost","root",""); //connect to your database
mysql_select_db("test"); //select which database we're using
// Build MySql Query
$query = "select * from contacts where name like \"%$trimmed%\"
order by name"; // 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>";
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";
$count = 1 + $s ;
// now you can display the results returned
while ($row= mysql_fetch_array($result)) {
$title = $row["1st_field"];
echo "$count.) $title" ;
$count++ ;
}
$currPage = (($s/$limit) + 1);
//break before paging
echo "<br />";
// next we need to do the links to other results
if ($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>";http://www.designplace.org/forum/viewtopic.php?t=458
