問題描述

我正在嘗試使用 PHP 制作動態表.我有一個頁面顯示數據庫中的所有圖片.我只需要該表為 5 列.如果返回的圖片超過 5 張，則應創建一個新行，其余圖片將繼續顯示.

I'm trying to make a dynamic table with PHP. I have a page which displays all the pictures from a database. I need the table to be of 5 columns only. If more than 5 pictures are returned, it should create a new row and the displaying of the rest of the pics would continue.

有人可以幫忙嗎?

代碼在這里:主頁中的代碼:-

Codes go here: Code in the main page:-

    <table>
    <?php
        $all_pics_rs=get_all_pics();
        while($pic_info=mysql_fetch_array($all_pics_rs)){
        echo "<td><img src='".$pic_info['picture']."' height='300px' width='400px' /></td>";
            } 
?>
</table>

get_all_pics() 函數:

The get_all_pics() function:

$all_pics_q="SELECT * FROM pics";
        $all_pics_rs=mysql_query($all_pics_q,$connection1);
        if(!$all_pics_rs){
            die("Database query failed: ".mysql_error());
        }
        return $all_pics_rs;

此代碼正在創建單行.我想不出如何獲得多行...... !!

This code is creating a single row. I can't think of how I can get multiple rows ... !!

推薦答案

$maxcols = 5;
$i = 0;

//Open the table and its first row
echo "<table>";
echo "<tr>";
while ($image = mysql_fetch_assoc($images_rs)) {

    if ($i == $maxcols) {
        $i = 0;
        echo "</tr><tr>";
    }

    echo "<td><img src="" . $image['src'] . "" /></td>";

    $i++;

}

//Add empty <td>'s to even up the amount of cells in a row:
while ($i <= $maxcols) {
    echo "<td>&nbsp;</td>";
    $i++;
}

//Close the table row and the table
echo "</tr>";
echo "</table>";

我還沒有測試過，但我的瘋狂猜測是這樣的.只需使用圖像循環瀏覽數據集，只要您還沒有制作 5 個 <td>，就添加一個.到達 5 后，關閉該行并創建一個新行.

I haven't tested it yet but my wild guess is something like that. Just cycle through your dataset with the images and as long as you didn't make 5 <td>'s yet, add one. Once you reach 5, close the row and create a new row.

這個腳本應該給你類似下面的東西.這顯然取決于您擁有的圖像數量，我假設 5(在 $maxcols 中定義)是您想要連續顯示的最大圖像數量.

This script is supposed to give you something like the following. It obviously depends on how many images you have and I assumed that 5 (defined it in $maxcols) was the maximum number of images you want to display in a row.

<table>
    <tr>
        <td><img src="image1.jpg" /></td>
        <td><img src="image1.jpg" /></td>
        <td><img src="image1.jpg" /></td>
        <td><img src="image1.jpg" /></td>
        <td><img src="image1.jpg" /></td>
    </tr>
    <tr>
        <td><img src="image1.jpg" /></td>
        <td><img src="image1.jpg" /></td>
        <td>&nbsp;</td>
        <td>&nbsp;</td>
        <td>&nbsp;<td>
    </tr>
</table>
