Question

使用TCPDF制作PDF时，每5 <tr>后获得一个新的<td>会遇到一些问题：

$bricks = "";
$bricks .= '<table>';
$bricks .= '<tr>';

foreach($bricks_selected as $key => $value) {
    $num_check = substr($value, 4);

    if($num_check != "0") {                
        $bricks .= '<td width="90" height="80"><img src="/var/www/brickmixer/bricks/tavler/RT'.substr($value, 0, 3).'.jpg" width="80" height="55"><br><b>RT '. substr($value, 0, 3) .' - '. $num_check .'%</b></td>';       
    } 

}

我曾尝试过分组等，但它给了我一些有趣的结果。

$bricks_selected变量在脚本顶部设置：

foreach($_POST as $key => $value) {
    if($key == "bricks-selected") {
        $bricks_selected = explode("&", $value);
    }
}

添加增量变量并检查每5 td个：

$i = 1;
foreach($bricks_selected as $key => $value) {
    $num_check = substr($value, 4);
    if($num_check != "0") {                
        $bricks .= '<td width="90" height="80"><img src="/var/www/brickmixer/bricks/tavler/RT'.substr($value, 0, 3).'.jpg" width="80" height="55"><br><b>RT '. substr($value, 0, 3) .' - '. $num_check .'%</b></td>';       
    } 
    if($i%5 == 0){
         echo '</tr><tr>';
    }
    $i++;
}

Answer 2

您尝试制作增量变量，例如$ i和if ($i%5==0) {/* you have to close </tr> and open new <tr>*/} else {/* you do other thing*/}

php和tcpdf中5 td后的新tr
