根據MySQL查詢輸出設置單元格的背景顏色

Question

我是PHP新手，嘗試學習足夠的基本功能。我已經能夠爲我的用戶創建一個表格來編輯自己，並重新顯示，但我遇到了一個問題。 使用下面的腳本，用戶可以輸入他們的各種產品的技能水平。我希望能夠突出顯示它們輸入「0」或空白的每個單元格。用戶的輸入將在0-5之間（如果還沒有填入，則輸入空白）。

這一切都在我的本地主機上完成，所以我承認所有的安全措施都不在那裏。

我已經閱讀了很多文章，並試圖找出自己，但我正在做一些根本性錯誤，我相信。

任何這方面的援助將不勝感激。我已經知道買啤酒（通過PayPal）對於那些誰幫我編碼:)

這裏是我現有的用於打印出數據庫的結果代碼：

<?php 
//This will connect to the database in order to begin this page 
mysql_connect("localhost", "root", "time2start") or die (mysql_error()); 
//Now we will select the database we need to talk to 
mysql_select_db("joomla_dev_15") or die (mysql_error()); 
$query = "SELECT * FROM enterprise_storage WHERE id=1"; 
$result = mysql_query($query) or die (mysql_error()); 
echo "<table border='1'>"; 
echo "$row"; 
echo "<tr> <th>Product</th> <th>Wayne Beeg</th> <th>Paul Hamke</th> <th>Steve Jaczyk</th>  <th>David Jontow</th> <th>Ed MacDonald</th> <th>Michael Munozcano</th> <th>Ron Shaffer</th> <th>Luke Soares</th> <th>Josh Wenger</th> </tr>"; 
// keeps getting the next row until there are no more to get 
while($row = mysql_fetch_array($result)) { 
// Print out the contents of each row into a table 
echo "<tr><td>"; 
echo $row['model']; 
echo "</td><td>"; 
echo $row['beeg']; 
echo "</td><td>"; 
echo $row['hamke']; 
echo "</td><td>"; 
echo $row['jaczyk']; 
echo "</td><td>"; 
echo $row['jontow']; 
echo "</td><td>"; 
echo $row['macdonald']; 
echo "</td><td>"; 
echo $row['munozcano']; 
echo "</td><td>"; 
echo $row['shaffer']; 
echo "</td><td>"; 
echo $row['soares']; 
echo "</td><td>"; 
echo $row['wenger']; 
echo "</td></tr>"; 
} 
echo "</table>"; 
?> 
<FORM> 
<INPUT TYPE="BUTTON" VALUE="Return to the Home Page"  ONCLICK="window.location.href='http://localhost/~user/joomla15/custom/skilldisplay.php'"> 
</FORM> 

Answer 1

也許

while($row = mysql_fetch_array($result)) { 
// Print out the contents of each row into a table 
echo "<tr>"; 
foreach($row as $content) { 
    if($content == 0) { 
     echo "<td style='background-color:gray;'>"; 
    } 
    else { 
     echo "<td style='background-color:green;'>"; 
    } 
    echo $content . "</td>"; 
} 
echo $row['wenger']; 
echo "</td>"; 
} 
echo "</tr></table>"; 

Answer 2

嘗試這樣的事情

添加到您的生成文檔的

<style type="text/css"> 
    .red{ background-color: red; } 
</style> 

這是你的PHP：

<?php 
// sanitize value 
$value = trim($row['model']); 
$class = (empty($value)) ? 'red' : ''; 

// display 
echo "<td class=\"$class\">$value</td>"; 
... 
?> 

Answer 3

好了，我設法得到它最後的工作。上面的兩個回覆幫助我找出了正確的做法。

當然，我的方法可能不是最好的方法，但我已經測試過，它適用於我的需要。對於任何未來的搜索，這是我做的：

<?php 
    //This will connect to the database in order to begin this page 
    mysql_connect("localhost", "root", "time2start") or die (mysql_error()); 
    //Now we will select the database we need to talk to 
    mysql_select_db("joomla_dev_15") or die (mysql_error()); 
    $query = "SELECT * FROM enterprise_storage"; 
    $result = mysql_query($query) or die (mysql_error()); 
    echo "<table border='1'>"; 
    echo "$row"; 
    echo "<tr> <th>Product</th> <th>Wayne Beeg</th> <th>Paul Hamke</th> <th>Steve Jaczyk</th> <th>David Jontow</th> <th>Ed MacDonald</th> <th>Michael Munozcano</th> <th>Ron Shaffer</th> <th><a href='http://localhost/~user/joomla15/custom/updateform.php'>Luke Soares</a></th> <th>Josh Wenger</th> </tr>"; 
    // keeps getting the next row until there are no more to get 
    while($row = mysql_fetch_array($result)) { 
// Print out the contents of each row into a table 
echo "<tr><td>"; 
echo $row['model']; 
echo "</td>"; 
if ($row['beeg'] == '0'){ 
    echo '<td bgcolor="#FF0000">' . $row['beeg'] ; 
}else{ 
    echo '<td>' .$row['beeg']; 
} 
echo "</td>"; 
if ($row['hamke'] == '0'){ 
    echo '<td bgcolor="#FF0000">' . $row['hamke'] ; 
}else{ 
    echo '<td>' .$row['hamke']; 
} 
echo "</td>"; 
if ($row['jaczyk'] == '0'){ 
    echo '<td bgcolor="#FF0000">' . $row['jaczyk'] ; 
}else{ 
    echo '<td>' .$row['jaczyk']; 
} 
echo "</td>"; 
if ($row['jontow'] == '0'){ 
    echo '<td bgcolor="#FF0000">' . $row['jontow'] ; 
}else{ 
    echo '<td>' .$row['jontow']; 
} 
echo "</td>"; 
if ($row['macdonald'] == '0'){ 
    echo '<td bgcolor="#FF0000">' . $row['macdonald'] ; 
}else{ 
    echo '<td>' .$row['macdonald']; 
} 
echo "</td>"; 
if ($row['munozcano'] == '0'){ 
    echo '<td bgcolor="#FF0000">' . $row['munozcano'] ; 
}else{ 
    echo '<td>' .$row['munozcano']; 
} 
echo "</td>"; 
if ($row['shaffer'] == '0'){ 
    echo '<td bgcolor="#FF0000">' . $row['shaffer'] ; 
}else{ 
    echo '<td>' .$row['shaffer']; 
} 
echo "</td>"; 
if ($row['soares'] == '0'){ 
    echo '<td bgcolor="#FF0000">' . $row['soares'] ; 
}else{ 
    echo '<td>' .$row['soares']; 
} 
echo "</td>"; 
if ($row['wenger'] == '0'){ 
    echo '<td bgcolor="#FF0000">' . $row['wenger'] ; 
}else{ 
    echo '<td>' .$row['wenger']; 
} 
echo "</td></tr>"; 

} 回聲 「」;
