Question

我正在尝试按类别显示上传的简历，这是在下拉列表中，当我选择网页设计师时，它会显示所有上传的网页设计师简历，但如果关键字与任何类别不匹配，那么它应该显示消息＆＃34;此类别中没有找到简历＆＃34;，如果可以的话，我希望我是php新手，请帮助我。感谢

<?php

$cat=$_GET['cat']; // Security will be added here.

$results = mysql_query("SELECT * FROM resumes where profile like '%$cat%' ORDER BY id desc LIMIT 0, 50000");

while($row = mysql_fetch_array($results)) {

$anymatches = mysql_num_rows($results);

?>

在这里，我想展示信息。

<?php if ($anymatches == 0) { ?><font color="#990000"></p>No resumes found in this category.</font><?php } ?>

完整页面在这里---

<?php include "inc.php";

$cat=$_REQUEST['cat'];
$cat=str_replace(' ','%',$_REQUEST['cat']);

if(!isset($_SESSION['ocer'])){
header("Location: index.php?l=1");
}

if(isset($_REQUEST['action']) && $_REQUEST['action']=="del"){
$sql_del="delete from resumes  where id='".$_REQUEST['idm']."'";
mysql_query($sql_del) or die(mysql_error());

header("Location: resumes_by_cat.php?del=1");
}
$mydtl="select * from register where email='".$_SESSION['ocer']."'";
$mydtl1=mysql_query($mydtl) or die(mysql_error());

Answer 1

mysql_num_rows不应该在你的while循环中。如果你将它移到循环之后，只要你的sql查找正确，你的代码应该可以正常工作。

像这样：

while($row = mysql_fetch_array($results)) {
    //output your resumes here
}
if( mysql_num_rows($results)==0 ) echo "<p>No resumes found in this category.</p>";

Answer 2

希望此代码能为您提供帮助。

<?php

    $cat=$_GET['cat']; // Security will be added here.

    $results = mysql_query("SELECT * FROM resumes where profile like '%$cat%' ORDER BY id desc LIMIT 0, 50000");

    // Dont place mysql_num_rows inside loop
    // It returns same value only if its inside in loop
    $anymatches = mysql_num_rows($results); 

    //If mysql_num_rows has more than 0 let run in loop
    if($anymatches > 0){

        while($row = mysql_fetch_array($results)) {

            //loop so on

        }       

    }else{ // else number of rows is 0 print your message

        echo '<p>No resumes found in this category.</p>';       

    }    

?>

Answer 3

解决问题!!

我在代码的顶部添加了这两行。

$results = mysql_query("SELECT * FROM resumes where profile like '%$cat%' ORDER BY id desc LIMIT 0, 50000");
$anymatches = mysql_num_rows($results);

如果关键字不匹配，如何显示消息
