警告:mysql_num_rows()預計參數1是資源,布爾在/storage/ssd5/102/3255102/public_html/search.php給出線29PHP警告同時使搜索引擎
我的代碼:
<?php
$button = $_GET [ 'submit' ];
$search = $_GET [ 'search' ];
if(!$button)
echo "you didn't submit a keyword";
else {
if(strlen($search) <= 1)
echo "Search term too short";
else {
echo "You searched for <b> $search </b> <hr size='1' > </ br > ";
mysql_connect("localhost","id3255102_data","I AM NOT GOING TO TELL YOU MY PASS!") ;
mysql_select_db("id3255102_base");
$search_exploded = explode (" ", $search);
$x = 0;
foreach($search_exploded as $search_each) {
$x++;
$construct = "";
if($x == 1)
$construct .="keywords LIKE '%$search_each%'";
else
$construct .="AND keywords LIKE '%$search_each%'";
}
$construct = " SELECT * FROM SEARCH_ENGINE WHERE $construct ";
$run = mysql_query($construct);
$foundnum = mysql_num_rows($run);
if ($foundnum == 0)
echo "Sorry, there are no matching result for <b> $search </b>. </br> </br> 1. Try more general words. for example: If you want to search 'how to create a website' then use general keyword like 'create' 'website' </br> 2. Try different words with similar meaning </br> 3. Please check your spelling";
else {
echo "$foundnum results found !<p>";
while($runrows = mysql_fetch_assoc($run)) {
$title = $runrows ['title'];
$desc = $runrows ['description'];
$url = $runrows ['url'];
echo "<a href='$url'> <b> $title </b> </a> <br> $desc <br> <a href='$url'> $url </a> <p>";
}
}
}
}
?>

回聲你的查詢是否有效 – urfusion
檢查你的查詢結果集中的行數是否成功或失敗時是否爲FALSE。 – honarkhah
您使用的是完全過時的mysql連接器,這個連接器已經過時多年了,並且自從PHP版本7以來實際上已經被完全刪除。結果,您的代碼對sql注入攻擊全面開放。請閱讀將「準備好的語句」與「參數綁定」組合使用以避免此類漏洞的優點。 – arkascha
