您好,我设法将一个简单的搜索引擎作为其基础,所以我开始研究它。但我被禁止访问,不知道为什么有人可以帮助我?用一个表格,我给 $find 我搜索的词,它应该搜索它。谢谢你的时间!`
<?php
if ($searching =="yes")
{
echo "Results";
if ($find == "")
{
echo "You forgot to enter a search term";
exit;
}
mysql_connect("localhost","Anton","zouzou13") or die(mysql_error()); mysql_select_db("Ptyxiakh") or die(mysql_error());
$find = strtoupper($find);
$find = strip_tags($find);
$find = trim ($find);
$data =mysql_query("SELECT * FROM documents WHERE keywords LIKE'%$find%'");
while($result = mysql_fetch_array( $data ))
{
echo $result['document_name'];
echo " ";
echo $result['first_paragraph'];
echo "<br>";
}
$anymatches=mysql_num_rows($data);
if ($anymatches == 0)
{
echo "Sorry, but we can not find an entry to match your query<br><br>"; }
echo "<b>Searched For:</b> " .$find; } ?>
ok i made it simpler to see if it works like this:
<?php
error_reporting(E_ALL);
mysql_connect("localhost","Anton","zouzou13") or die(mysql_error());
mysql_select_db("Ptyxiakh") or die(mysql_error());
//Now we search for our search term, in the field the user specified
$data = mysql_query("SELECT * FROM documents WHERE keywords LIKE 'helmets'");
while($result = mysql_fetch_array( $data ))
{
echo $result['document_name'];
echo " ";
echo $result['first_paragraph'];
echo "<br>";
}
$anymatches=mysql_num_rows($data);
if ($anymatches == 0)
{
echo "Sorry, but we can not find an entry to match your query<br><br>";
}
?>
But i get the "Sorry, but we can not find an entry to match your query<br><br>"; so i cant connect to database?its just wont work :(
With PDO it should be like this??:
<?php
//This is only displayed if they have submitted the form
if ($searching =="yes")
{
echo "<h2>Results</h2><p>";
//If they did not enter a search term we give them an error
if ($find == "")
{
echo "<p>You forgot to enter a search term";
exit;
}
$pdo = new PDO('mysql:host=localhost;dbname=ptyxiakh', 'Anton', 'zouzou13');
// Otherwise we connect to our Database
//mysql_connect("localhost","Anton","zouzou13") or die(mysql_error());
//mysql_select_db("Ptyxiakh") or die(mysql_error());
// We preform a bit of filtering
$find = strtoupper($find);
$find = strip_tags($find);
$find = trim ($find);
//Now we search for our search term, in the field the user specified
//$data = mysql_query("SELECT * FROM documents WHERE keywords LIKE'%$find%'");
$data= $pdo->query("SELECT * FROM documents WHERE keywords LIKE'%$find%'");
//And we display the results
while($row = $statement->fetch(PDO::FETCH_ASSOC))
{
echo htmlentities($row['document_name']);
echo " ";
echo htmlentities($row['first_paragraph']);
echo "<br>";
}
//This counts the number or results - and if there wasn't any it gives them a little message explaining that
$anymatches=mysql_num_rows($data);
if ($anymatches == 0)
{
echo "Sorry, but we can not find an entry to match your query<br><br>";
}
//And we remind them what they searched for
echo "<b>Searched For:</b> " .$find;
}
?>
