我希望每个表行显示每个不同的数据库记录,但是我无法为每个行和列检索不同的记录。请给我一些建议,我可以粘贴而不是阻止,因此它会为每一行和每列提供不同的结果。
<?php
$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = '';
$rec_limit = 10;
$scriptname=$_SERVER['PHP_SELF'];
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db('online_shopping'); // include your code to connect to DB.
$tbl_name="mobile_db"; //your table name
$start = 0;
$limit = 5;
$sql = "SELECT id,company,model,price,availability,image FROM $tbl_name LIMIT $start, $limit";
$result = mysql_query($sql);
while($row = mysql_fetch_array($result))
{
$company=$row['company'];
$model=$row['model'];
$available=$row['availability'];
$price=$row['price'];
}
echo "<table border='2'>";
$j = 0;
for($j = 0; $j<5; $j++)
{
echo "<tr>";
for($i = 0; $i<3; $i++)
{
echo "<td>";
echo "<table border='2'>";
echo "<tr>";
echo "<td><img src='abc.jpg' height='250' width='250'/></td>";
echo "</tr>";
echo "<tr>";
echo "<td>";
echo "<table border='2'>";
echo "<tr>";
echo "<td><b>Brand : </b></td>";
echo '<td>'.$company.'</td>';
echo "</tr>";
echo "<tr>";
echo "<td><b>Model : </b></td>";
echo '<td>'.$model.'</td>';
echo "</tr>";
echo "<tr>";
echo "<td><b>Availability : </b></td>";
echo '<td>'.$available.'</td>';
echo "</tr>";
echo "<tr>";
echo "<td><b>Price : </b></td>";
echo '<td>'.$price.'</td>';
echo "</tr>";
echo "</table>";
echo "</td>";
echo "</tr>";
echo "</table>";
echo "</td>";
}
echo "</tr>";
}
echo "</table>";
?>

在你的while
循环中,你总是重写相同的变量,循环后你只保存了最后一条记录。
在循环中,您必须将记录保存到数组中。
在您的代码中,您有嵌套表,但在第一个中,只有一行和一个表单元格包含另一个表。我只使用嵌套表。
<?php
...
$result = mysql_query($sql);
$data = array();
while($row = mysql_fetch_array($result)) {
$data[] = $row;
}
if (count($data) > 0) {
echo '<table>';
foreach ($data as $row) {
echo '<tr>';
echo '<td>Brand: ' . $row['company'];
echo '<td>Model: ' . $row['model'];
echo '<td>Availability: ' . $row['availability'];
echo '<td>Price: ' . $row['price'];
}
echo '</table>';
} else {
echo 'no records';
}
?>

不确定我是否完全理解你想要完成的事情,但试试这个。
<?php
$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = '';
$rec_limit = 10;
$scriptname=$_SERVER['PHP_SELF'];
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db('online_shopping'); // include your code to connect to DB.
$tbl_name="mobile_db"; //your table name
$start = 0;
$limit = 5;
$sql = "SELECT id,company,model,price,availability,image FROM $tbl_name LIMIT $start, $limit";
$result = mysql_query($sql);
echo "<table border='2'>";
while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>".$row['company']."</td>";
echo "<td>".$row['model']."</td>";
echo "<td>".$row['availability']."</td>";
echo "<td>".$row['price']."</td>";
echo "</tr>";
}
echo "</table>";
?>

您需要将表格行移动到取道循环中,或将行存储在数组中。我简化了表格以使示例更清晰:
$result = mysql_query($sql);
if (!$result) {
/* Error */
}
echo '<table>';
while ($row = mysql_fetch_array($result)) {
echo '<tr><td><img src="', htmlspecialchars ($row['image']), '">';
echo '<tr><td><table>';
echo ' <tr><th>Brand<td>', htmlspecialchars ($row['company']);
echo ' <tr><th>Model<td>', htmlspecialchars ($row['model']);
echo ' <tr><th>Availability<td>', htmlspecialchars ($row['availability']);
echo ' <tr><th>Price<td>', htmlspecialchars ($row['price']);
echo ' </table>';
}
echo "</table>\n";
