Question

我想知道使用foreach循环我的代码是否更容易。我的代码如此：目的是读取MYSQL表中的值，如果anwser是＆＃34; NEE＆＃34;以红色显示背景颜色。我的代码有效，但很长..

$connection = mysql_connect('localhost', 'root', ''); //The Blank string is 
the password
mysql_select_db('heijsDB');

$query = "SELECT * FROM hygieneaanvoer"; //You don't need a ; like you do in 
SQL
$result = mysql_query($query);

//List the Columns for the Report 
if(! $result ) {
           die('Could display data: ' . mysql_error());
        }

echo "<table border='1' class='w3-panel'> 
<fieldset>hygiëne/GMP aduit Aanvoer</fieldset>
<tr> 
<th>Datum</th> 
<th>Controleur</th> 
<th>controleur</th>
<th>Revisie</th>

while($row = mysql_fetch_array($result))

Answer 1

您可以做的只是创建一个用于设置所有行样式的变量：

while($row = mysql_fetch_array($result)) 
{ 
    $style_string = "";
    if($row['q1']=='NEE') {
        $style_string = "style='background-color: #e21010;'";
    }

    echo "<tr>"; 
    echo "<td>" . $row['datum'] . "</td>"; 
    echo "<td>" . $row['controleur'] . "</td>";
    echo "<td>" . $row['codering'] . "</td>"; 
    echo "<td>" . $row['revisie'] . "</td>";
    echo "<td " . $style_string . ">" . $row['q1'] . "</td>";
    echo "<td " . $style_string . ">" . $row['q2'] . "</td>";
    echo "<td " . $style_string . ">" . $row['q3'] . "</td>";
    echo "<td " . $style_string . ">" . $row['q4'] . "</td>";
    echo "<td " . $style_string . ">" . $row['q5'] . "</td>";
    echo "<td " . $style_string . ">" . $row['q6'] . "</td>";
    echo "<td " . $style_string . ">" . $row['q7'] . "</td>";
    echo "<td " . $style_string . ">" . $row['q8'] . "</td>";
    echo "<td " . $style_string . ">" . $row['q9'] . "</td>";
    echo "<td " . $style_string . ">" . $row['q10'] . "</td>";
    echo "<td " . $style_string . ">" . $row['q11'] . "</td>";
    echo "<td " . $style_string . ">" . $row['q12'] . "</td>";
    echo "<td " . $style_string . ">" . $row['q13'] . "</td>";
    echo "<td " . $style_string . ">" . $row['q14'] . "</td>";
    echo "<td " . $style_string . ">" . $row['q15']. "</td>";
    echo "</tr>"; 
 }

（或者只设置<tr>）

的背景颜色

祝你好运！

Answer 2

您只需将该类添加到td，就像这样

echo "<td class='". $row['q15'] . "'>".$row['q15']."</td>";

像这样添加css

.NEE {background-color: #e21010;}

Answer 3

这是解决方案

$result = mysql_query("SELECT * FROM hygieneaanvoer")or die('Could display data: ' . mysql_error());;

echo "<table border='1' class='w3-panel'> 
<fieldset>hygiëne/GMP aduit Aanvoer</fieldset>
<tr> 
<th>Datum</th> 
<th>Controleur</th> 
<th>controleur</th>
<th>Revisie</th>";

for ($i=1;$i<=15;$i++){
    echo '<th>'.$i.'</th>';
} 
echo "</tr>"; 
while($row = mysql_fetch_array($result))  { 
    echo "<tr>"; 
    echo "<td>" . $row['datum'] . "</td>"; 
    echo "<td>" . $row['controleur'] . "</td>";
    echo "<td>" . $row['codering'] . "</td>"; 
    echo "<td>" . $row['revisie'] . "</td>";
    for ($j=1;$j<=15;$j++){
        echo "<td ".(($row['q'.$j] == 'NEE') ? "style='background-color: #e21010;'" : "" ).">".$row['q'.$j]."</td>";
    }
    echo "</tr>"; 
} 
echo "</table>";

?>
