TCPDF：通過'foreach'方法設置幾個圖像之間的邊距

Question

我正在使用TCPDF，我試圖設置行和列排版在pdf圖像上通過foreach方法獲取。 這裏是我的代碼：

$imagesValues = get_post_meta($post->ID, 'image'); 
foreach ($imagesValues as $imageItem) { 
    foreach ($imageItem as $imageID) { 
     $imageURL = wp_get_attachment_url($imageID); // gets photo URL 
     $pdf->Image($gallerieURL, $x, $y, $w, $h, 'JPG', '', '', false, 300, '', false, false, 0, false, false, false); 
    } 
} 

編輯

我已經做到了：

$x = 115; 
$y = 35; 
$w = 25; 
$h = 50; 
foreach ($imagesValues as $imageItem) { 
    foreach ($imageItem as $imageID) { 
    $imageURL = wp_get_attachment_url($imageID); // gets photo URL 
    $x = 115; 
    for ($i = 0; $i < 2; ++$i) { 
     $pdf->Image($imageURL, $x, $y, $w, $h, 'JPG', '', '', false, 300, '', false, false, 0, false, false, false); 
     $x += 27; // new column 
    } 
    $y += 52; // new row 
    } 
} 

但是，同樣的圖像重複自己

Answer 1

我建議你改變你的數據來源看起來像：

array (
    0 => array (
    'w'=>320, 
    'h'=>240 
), 
    1 => array (
    'w'=>300, 
    'h'=>250 
) 
) 

不過沒關係，你需要簡單地在這裏做一些計算：

// Assuming that 115 is the width of the row 
$x = 0; 
// Assuming that 52 is the height of each 
$y = 0; 
$w = 25; 
$h = 50; 

// We start on 1 image, there are 4 images in each row 
$imageCounter = 1; 

foreach ($imagesValues as $imageItem) { 
    foreach ($imageItem as $imageID) { 
    // gets photo URL 
    $imageURL = wp_get_attachment_url($imageID); 
    // Calculate the column and row specifications 
    switch ($imageCounter) { 
     // First column 
     case 1: 
     $x = 0; 
     $imageCounter ++; 
     break; 
     case 2: 
     $x = 27; 
     $imageCounter ++; 
     break; 
     case 3: 
     $x = 54; 
     $imageCounter ++; 
     break; 
     case 4: 
     $x = 81; 
     // Reset the image counter back to 1 for the new row 
     $imageCounter = 1; 
     // New row 
     $y += 52; 
     break; 
    } 
    $pdf->Image($imageURL, $x, $y, $w, $h, 'JPG', '', '', false, 300, '', false, false, 0, false, false, false); 
    }  
}
