MNSarahG Posted April 17, 2008 Share Posted April 17, 2008 Hi, I'm trying to run a search of table in my database. I have a page with this form: <form name="form" action="results.php" method="get"> <input type="text" name="q" /> <input type="submit" name="Submit" value="Search!" /> </form> That then uses this code to execute a search: <?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 search...</p>"; exit; } // check for a search parameter if (!isset($var)) { echo "<p>We dont seem to have a search parameter!</p>"; exit; } mysqli_connect("localhost","meetings","m33tings123"); mysqli_select_db("meetingsEventLocation") or die("Unable to select database"); // Build SQL Query $query = "select * from listings where name like \"%$trimmed%\" order by name"; $numresults=mysqli_query($query); $numrows=mysqli_num_rows($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"; $result = mysqli_query($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= mysqli_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>"; } $a = $s + ($limit) ; if ($a > $numrows) { $a = $numrows ; } $b = $s + 1 ; echo "<p>Showing results $b to $a of $numrows</p>"; ?> As of now, my error is "Unable to select database." I have triple checked my username, PW, database name, location, and all that, so I think it's coming from my attempt to change this code to work with MySQLi. Does anyone have any ideas?

GingerRobot Posted April 17, 2008 Share Posted April 17, 2008 Echo the error that mysql gives: mysqli_select_db("meetingsEventLocation") or die("Unable to select database<br />".mysqli_error()); Quote Link to comment Share on other sites More sharing options...
MNSarahG Posted April 17, 2008 Author Share Posted April 17, 2008 Hey, I pasted that code into the file and it still just comes back with "Unable to Select Database" (no extra info). - Sarah - Quote Link to comment Share on other sites More sharing options...
GingerRobot Posted April 17, 2008 Share Posted April 17, 2008 Looks like you need the mysqli_connect_error() function rather than mysqli_error(). Try that and see what it says. Quote Link to comment Share on other sites More sharing options...
MNSarahG Posted April 17, 2008 Author Share Posted April 17, 2008 This (like all of these problems) is blowing my mind. I changed my connect statement to this: mysqli_connect("localhost","meetings","m33tings123","meetingsEventLocation") or die("<strong>Couldn't connect to database</strong>".mysqli_connect_error()); And now it seems to connect to the DB okay. Now my error is "Couldn't execute query." Not sure why. Thanks again for any advice! Quote Link to comment Share on other sites More sharing options...
