Question

我无法将数据回显到HTML表格中。

它是这样的：

Wrong one

但它应该是：

Correct one

这是代码。我做错了什么？

<?php
    $query = $_POST['query']; 
    $min_length = 1;

    if(strlen($query) >= $min_length){ // if query length is more or equal minimum length then

        $query = htmlspecialchars($query); 
        $query = mysql_real_escape_string($query);         
        $raw_results = mysql_query("SELECT * FROM norse5_proov
            WHERE (`model` LIKE '%".$query."%') OR (`year` LIKE '%".$query."%')") or die(mysql_error());

        if(mysql_num_rows($raw_results) > 0){ // if one or more rows are returned do following

            while($results = mysql_fetch_array($raw_results)){
                echo "<table>";
                echo "<tr>";
                        echo "<td>Model name</td>";
                echo "<td>Year</td>";
                echo "</tr>";
                echo "<td>".$results['mudeli_nimetus']."</td>";

                echo "<td>".$results['soetusaasta']."</td>";
                echo "<br>";
                echo "</table>";
            }

        }
        else{
            echo "No results";
        }

    }
?>

Answer 1

问题是你不断为每次迭代输出一个新表。

您的代码应如下所示：

<?php
$query = $_POST['query']; 
$min_length = 1;

if(strlen($query) >= $min_length){ // if query length is more or equal minimum length then

    $query = htmlspecialchars($query); 
    $query = mysql_real_escape_string($query);         
    $raw_results = mysql_query("SELECT * FROM norse5_proov
        WHERE (`model` LIKE '%".$query."%') OR (`year` LIKE '%".$query."%')") or die(mysql_error());

    if(mysql_num_rows($raw_results) > 0){ // if one or more rows are returned do following

        echo "<table>"; // Start the table
        // Output the table headers
        echo "<tr>";
        echo "<td>Model name</td>";
        echo "<td>Year</td>";
        echo "</tr>";

        while($results = mysql_fetch_array($raw_results)) {
            echo "<tr>";
            echo "<td>".$results['mudeli_nimetus']."</td>";
            echo "<td>".$results['soetusaasta']."</td>";
            echo "<br>";
            echo "</tr>";
        }

        echo "</table>"; // End the table

    }
    else{
        echo "No results";
    }

}
?>

Answer 2

只需将echo "<table>";和第一个tr创建语句放在while循环之外，并在完成table循环后关闭while，看看我确定它会起作用

尝试

<?php
    echo "<table><tr><td>Model name</td><td>Year</td></tr>";

    while($results = mysql_fetch_array($raw_results))
    {
        echo "<tr><td>".$results['mudeli_nimetus']."</td><td>".$results['soetusaasta']."</td></tr>";
    }
    echo "</table>";
?>

Answer 3

使用此代码，您必须先启动表，使用while循环迭代结果，然后关闭表。

echo "<table>";
echo "<tr>";
echo "<td>Model name</td>";
echo "<td>Year</td>";
echo "</tr>";
while($results = mysql_fetch_array($raw_results)){
    echo "<tr>";
    echo "<td>".$results['mudeli_nimetus']."</td>";
    echo "<td>".$results['soetusaasta']."</td>";
    echo "</tr>";         
}
echo "</table>";

Answer 4

从while循环中删除表代码并放在外面。

echo "<table>";
echo "<tr>";
echo "<td>Model name</td>";
echo "<td>Year</td>";
echo "</tr>";


while($results = mysql_fetch_array($raw_results)){
            echo "<tr>";
            echo "<td>".$results['mudeli_nimetus']."</td>";

            echo "<td>".$results['soetusaasta']."</td>";

            echo "</tr>";
}

echo "</table>";

Answer 5

替换你的if块，使用以下代码，希望它可以帮助你

if（mysql_num_rows（$ raw_results）＆gt; 0） {

        echo "<table>";
        echo "<tr>";
        echo "<td>Model name</td>";
        echo "<td>Year</td>";
        echo "</tr>";
    while($results = mysql_fetch_array($raw_results)){
        echo "<tr>";
        echo "<td>".$results['mudeli_nimetus']."</td>";
        echo "<td>".$results['soetusaasta']."</td>";
        echo "</tr>";
    }echo "</table>";
}
