用PHP创建一个动态表 [英] Creating a dynamic table with PHP
问题描述
我需要的表只有5列。如果返回超过5张照片,应该创建一个新行,剩下的照片的显示将会继续。
任何人都可以帮忙?
代码到这里:
主页中的代码: -
< 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:
$ 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;
此代码正在创建一行。我不能想到如何获得多行... !!
$ maxcols = 5;
$ i = 0;
//打开表和第一行
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 ++;
}
//添加空的< td>是连续的单元格数量:
while($ i <= $ maxcols){
echo< td>& nbsp;< / td>;
$ i ++;
}
//关闭表行和表
echo< / tr>;
echo< / table>;
我还没有测试过,但我的狂野猜测是这样的。只要循环浏览您的数据集与图像,只要你没有制作5 < td>
,添加一个。一旦达到5,关闭该行并创建一个新行。
此脚本应该给你如下所示。这显然取决于你有多少图像,我假设5(在 $ maxcols 中定义)是要显示在一行中的最大图像数。
< 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>
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.
Can anyone please help?
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>
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;
This code is creating a single row. I can't think of how I can get multiple rows ... !!
$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>";
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.
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>
