在php中包含sql數據的HTML表格（表格行取決於sql列）
[英]HTML table with sql data in php (table row depend by sql columns)
問題描述
您好，我在sql中獲得了此示例數據
$data = array(
array('id' => '1','name' => 'name1','surname' => 'surname1'),
array('id' => '2','name' => 'name2','surname' => 'surname2'),
array('id' => '3','name' => 'name3','surname' => 'surname3'),
array('id' => '4','name' => 'name4','surname' => 'surname4')
);
我想在html表中顯示，但我的代碼無法正常工作：
<?php
mysql_connect("localhost", "root", "");
mysql_select_db("test");
$select_data = "SELECT * FROM dane ORDER BY `id` DESC";
?>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html">
<meta charset="utf-8">
<title></title>
</head>
<body>
<table style="width: 100%;" border="1" cellspacing="5" cellpadding="5">
<thead>
<tr>
<th align="left" valign="middle">id</th>
<th align="center" valign="middle">name</th>
<th align="center" valign="middle">surname</th>
</tr>
</thead>
<?php
$result = mysql_query($select_data);
while ($data = mysql_fetch_row($result)) {
}
?>
<tbody>
<tr>
<td align="center" valign="middle"><?php echo $data['id']; ?></td>
<td align="center" valign="middle"><?php echo $data['name']; ?></td>
<td align="left" valign="middle"><?php echo $data['surname']; ?></td>
</tr>
</tbody>
</table>
</body>
</html>
但是我也不想html表中的行數取決於sql表中的列數。 例如，在這種情況下，我只想顯示三行（sql表中的三列）。 當我將列添加到sql表時，我希望html輸出表中的行動態增加。
有人可以幫我這個代碼嗎？

將代碼更改為此：
<tbody>
<?php
$result = mysql_query($select_data);
while ($data = mysql_fetch_row($result)) {
?>
<tr>
<td align="center" valign="middle"><?php echo $data['id']; ?></td>
<td align="center" valign="middle"><?php echo $data['name']; ?></td>
<td align="left" valign="middle"><?php echo $data['surname']; ?></td>
</tr>
<?php
}
?>
</tbody>
您正在關閉while循環，然后再顯示結果

您關閉while循環不正確：
<?php
mysql_connect("localhost", "root", "");
mysql_select_db("test");
$select_data = "SELECT * FROM dane ORDER BY `id` DESC";
$result = mysql_query($select_data);
?>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html">
<meta charset="utf-8">
<title></title>
</head>
<body>
<table style="width: 100%;" border="1" cellspacing="5" cellpadding="5">
<thead>
<tr>
<th align="left" valign="middle">id</th>
<th align="center" valign="middle">name</th>
<th align="center" valign="middle">surname</th>
</tr>
</thead>
<tbody>
<?php while ($data = mysql_fetch_row($result)):?>
<tr>
<td align="center" valign="middle"><?php echo $data['id']; ?></td>
<td align="center" valign="middle"><?php echo $data['name']; ?></td>
<td align="left" valign="middle"><?php echo $data['surname']; ?></td>
</tr>
<?php endwhile;?>
</tbody>
</table>
</body>
</html>
使用“ while（cond）：”和“ endwhile;” 命令比使用帶有大括號的封裝更好地看到了東西的起點和終點。
請考慮將數據庫包裝程序從mysql_切換到PDO或mysqli ，因為不再積極支持mysql。
您還可以改用：
<?php echo $data['id']?>
簡稱：
<?=$data['id']?>
在5.3之后，也可以不帶php短打開（我認為是5.3）

如果我正確理解您的問題，則希望返回的行數與表dane中的列數匹配。 下面的代碼應該做到這一點，我強烈建議使用mysqli。 從PHP 5.5.0開始不推薦使用mysql_query擴展名。
<?php
$db = new mysqli('localhost', 'root', '', 'test'); // server, user, pass, database
$table_name = 'dane'; // table
// Let's make sure we could establish a connection
if($db->connect_errno > 0){
die('Unable to connect to the database ' . $db->connect_error);
}
// Build our select to return column names only
$select_cols = "SELECT column_name FROM information_schema.columns WHERE table_name='$table_name'";
if(!$result = $db->query($select_cols)){
die('There was an error running the query.');
}
while($row = $result->fetch_assoc()){
$cols[] = $row['column_name']; // Store the columns to an array. It will be further used.
}
// Implode the column names to a comma delimited string to use in the next select. It's also a good practice not to use asterisk in your select statements
$table_headers = implode(',', $cols);
// Query for records with a limit to number columns in the $table_name
$select_data = "SELECT $table_headers FROM $table_name ORDER BY `id` DESC LIMIT 0 , $result->num_rows";
if(!$result = $db->query($select_data)){
die('There was an error running the query ' . $db->error);
}
while($row = $result->fetch_assoc()){
$data[] = $row; // Store the data into an array to be used in the html table
}
$db->close(); // Close our connection
?>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html">
<meta charset="utf-8">
<title></title>
</head>
<body>
<table style="width: 100%;" border="1" cellspacing="5" cellpadding="5">
<thead>
<tr>
<?php foreach ($cols as $k) : // Loop through columns ?>
<th align="center" valign="middle"><?php echo $k; ?></th>
<?php endforeach; ?>
</tr>
</thead>
<tbody>
<?php foreach ($data as $k) : // Loop through each $data array() ?>
<tr>
<?php foreach ($k as $v) : // Let's display the records ?>
<td align="center" valign="middle"><?php echo $v; ?></td>
<?php endforeach; ?>
</tr>
<?php endforeach; ?>
</tbody>
</table>
</body>
</html>
我還自由地將列名動態顯示為表標題，這將消除在列增加時稍后手動添加它們的需要。 如果您想手動創建它們，只需用以下內容替換頂部的php部分：
<?php
$db = new mysqli('localhost', 'root', '', 'test'); // server, user, pass, database
$table_name = 'dane'; // table
// Let's make sure we could establish a connection
if($db->connect_errno > 0){
die('Unable to connect to database [' . $db->connect_error . ']');
}
// Build our select to return column names only
$select_cols = "SELECT column_name FROM information_schema.columns WHERE table_name='$table_name'";
if(!$num_cols = $db->query($select_cols)){
die('There was an error running the query.');
}
$select_data = "SELECT * FROM $table_name ORDER BY `id` DESC LIMIT 0 , $num_cols->num_rows";
if(!$result = $db->query($select_data)){
die('There was an error running the query [' . $db->error . ']');
}
while($row = $result->fetch_assoc()){
$data[] = $row; // Store the data into array to be used in the html table
}
$db->close(); // Close our connection
// print_r('<pre>');
// print_r($data);
// print_r('</pre>');
?>
並調整<thead></thead>之間的html代碼。 整個樣本很快就放在一起了，因此可以根據需要進行改進和調整。 請檢查是否有錯字。
