Question

您好我刚接触php但我不能让这个动态列表在这里工作是代码..

<?php 
if (isset($_GET['id'])) {
    include "DocumentSystem/scripts/connect_to_mysql.php";
$id = preg_replace('#[^0-9]#i', '', $_GET['id']);
$dynamicList = "";
$sql = mysql_query("SELECT * FROM documents WHERE id='$id' LIMIT 1");
$documentCount = mysql_num_rows($sql); // count the output amount
if ($documentCount > 0) {
    while($row = mysql_fetch_array($sql)){ 
             $id = $row["id"];
             $document_name = $row["document_name"];
             $full_document = $row["full_document"];
             $dynamicList .= '<div id="slidepic">
    <img src="images/document_images/'.$id.'.jpg" width="550" height="350" />
    <div id="slideshow">
    <h1> <a href="document.php?id='.$id.'">'.$document_name.'</a></h1>
    <br />
    <p1><a href="document.php?id='.$id.'">'.$full_document.'</a></p1>
    </div>
</div>';
    }
} else {
    $dynamicList = "We have no documents listed in the database";
}
mysql_close();
?>

它从网址获取正确的ID，但查询不适合我 thx任何答案！

Answer 1

尝试使用mysql_fetch_array($sql,MYSQL_ASSOC)或mysql_fetch_assoc($sql)代替mysql_fetch_array($sql) 默认情况下，mysql_fetch_array返回非关联数组。

注意：

不要SELECT * FROM table_name。使用SELECT column1, colum2 FROM table_name
不推荐使用Mysql模块。最好使用PDO mysql module page MySQL API comparison

Answer 2

请使用您已获得查询结果

<?php
$con = mysql_connect("localhost","username","password");
mysql_select_db("your_database_name", $con);
$result = mysql_query("SELECT * FROM documents WHERE id = '$id' LIMIT 1");
while($row = mysql_fetch_array($result))
{
  echo = $row["id"];
  echo = $row["document_name"];
  echo = $row["full_document"];
}

mysql_close($con);
?>

动态列表无法正常工作
