问题描述
我正在尝试使用 PHP 制作动态表.我有一个页面显示数据库中的所有图片.我只需要该表为 5 列.如果返回的图片超过 5 张，则应创建一个新行，其余图片将继续显示.
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.
有人可以帮忙吗?
代码在这里:主页中的代码:-
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() 函数:
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;
此代码正在创建单行.我想不出如何获得多行...... !!
This code is creating a single row. I can't think of how I can get multiple rows ... !!
推荐答案
$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> </td>";
$i++;
}
//Close the table row and the table
echo "</tr>";
echo "</table>";
我还没有测试过，但我的疯狂猜测是这样的.只需使用图像循环浏览数据集，只要您还没有制作 5 个 <td>，就添加一个.到达 5 后，关闭该行并创建一个新行.
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.
这个脚本应该给你类似下面的东西.这显然取决于您拥有的图像数量，我假设 5(在 $maxcols 中定义)是您想要连续显示的最大图像数量.
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> </td>
<td> </td>
<td> <td>
</tr>
</table>
