我正在尝试在HTML表中显示具有特定类别的数据库中的所有产品。但是我不确定如何将表限制为仅三列。
这是我的代码:
<table>
<?php
$catagory=$_GET["q"];
$con = mysql_connect("localhost","cl49-XXX","XXX");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("cl49-XXX", $con)or die( "Unable to select database");
$result=mysql_query("SELECT * FROM products WHERE catagory = '$catagory' ")or die('You need enter a catagory ' );
for ($i = 0; $i < mysql_num_rows($result); $i++)
{
$row = mysql_fetch_array($result);
$prodname = $row['prodname'];
$prodID = $row['prodID'];
if ($i % 5 == 0 || $i == 0) {
echo "<tr>";
}
echo "
<td>
<b>$prodname </b><br />
Product ID: $prodID<br />
<img src='/userpics/$prodID.jpg' height='200' width='200'>
</td>";
if ($i % 3 == 0 || $i == (mysql_num_rows($result)-1)) {
echo "</tr>";
}
}
?>
<table>
我正在等待在同一“单元格”中全部显示prodID,prodtitle和图片,但只有三列(每行三个产品)。
我该怎么做呢?
最佳答案
echo "<tr>"; // first row beginning
for ($i = 1; $i <= mysql_num_rows($result); $i++)
{
$row = mysql_fetch_array($result);
$prodname = $row['prodname'];
$prodID = $row['prodID'];
echo "
<td>
<b>$prodname </b><br />
Product ID: $prodID<br />
<img src='/userpics/$prodID.jpg' height='200' width='200'>
</td>";
if ($i % 3 == 0) {
echo "</tr> <tr>"; // it's time no move to next row
}
}
echo "</tr>"; // last row ending
请注意,$ i现在从1开始,并且在num_rows的
<=
而不是<
时循环。关于php - PHP数组到HTML表中,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/18017820/
