Merhaba arkadaşlar. PHP bilmediğimden şu sorunu halledemedim. Sizlerden yardım bekliyorum. wp-includes/media.php dosyasında 2 tane fonksiyondan birinde işe yarayan bir değişken diğerinde işe yaramıyor. Değişken şu: esc_attr($alt)

Fonksiyonlar ise şunlar;

1. Fonksiyon

function get_image_tag($id, $alt, $title, $align, $size='medium') {

list( $img_src, $width, $height ) = image_downsize($id, $size);
$hwstring = image_hwstring($width, $height);

$title = $title ? 'title="' . esc_attr( $title ) . '" ' : '';

$class = 'align' . esc_attr($align) .' size-' . esc_attr($size) . ' wp-image-' . $id;

/**
* Filter the value of the attachment's image tag class attribute.
*
* @since 2.6.0
*
* @param string $class CSS class name or space-separated list of classes.
* @param int $id Attachment ID.
* @param string $align Part of the class name for aligning the image.
* @param string $size Optional. Default is 'medium'.
*/
$class = apply_filters( 'get_image_tag_class', $class, $id, $align, $size );

$html = '' . esc_attr($alt) . '';

/**
* Filter the HTML content for the image tag.
*
* @since 2.6.0
*
* @param string $html HTML content for the image.
* @param int $id Attachment ID.
* @param string $alt Alternate text.
* @param string $title Attachment title.
* @param string $align Part of the class name for aligning the image.
* @param string $size Optional. Default is 'medium'.
*/
$html = apply_filters( 'get_image_tag', $html, $id, $alt, $title, $align, $size );

return $html;
}


2. Fonksiyon:

function img_caption_shortcode( $attr, $content = null ) {
// New-style shortcode with the caption inside the shortcode with the link and image tags.
if ( ! isset( $attr['caption'] ) ) {
if ( preg_match( '#((?:]+>\s*)?]+>(?:\s*)?)(.*)#is', $content, $matches ) ) {
$content = $matches[1];
$attr['caption'] = trim( $matches[2] );
}
}

/**
* Filter the default caption shortcode output.
*
* If the filtered output isn't empty, it will be used instead of generating
* the default caption template.
*
* @since 2.6.0
*
* @see img_caption_shortcode()
*
* @param string $output The caption output. Default empty.
* @param array $attr Attributes of the caption shortcode.
* @param string $content The image element, possibly wrapped in a hyperlink.
*/
$output = apply_filters( 'img_caption_shortcode', '', $attr, $content );
if ( $output != '' )
return $output;

$atts = shortcode_atts( array(
'id' => '',
'align' => 'alignnone',
'width' => '',
'caption' => '',
'class' => '',
'alt' => '',
), $attr, 'caption' );

$atts['width'] = (int) $atts['width'];
if ( $atts['width'] < 1 || empty( $atts['caption'] ) )
return $content;

if ( ! empty( $atts['id'] ) )
$atts['id'] = 'id="' . esc_attr( $atts['id'] ) . '" ';

$class = trim( 'wp-caption ' . $atts['align'] . ' ' . $atts['class'] );

if ( current_theme_supports( 'html5', 'caption' ) ) {
return '
'
. do_shortcode( $content ) . '
' . $atts['caption'] . '
';
}

$caption_width = 10 + $atts['width'];

/**
* Filter the width of an image's caption.
*
* By default, the caption is 10 pixels greater than the width of the image,
* to prevent post content from running up against a floated image.
*
* @since 3.7.0
*
* @see img_caption_shortcode()
*
* @param int $caption_width Width of the caption in pixels. To remove this inline style,
* return zero.
* @param array $atts Attributes of the caption shortcode.
* @param string $content The image element, possibly wrapped in a hyperlink.
*/

$caption_width = apply_filters( 'img_caption_shortcode_width', $caption_width, $atts, $content );

$style = '';
if ( $caption_width )
$style = 'style="width: ' . (int) $caption_width . 'px" ';

return '

' . $atts['caption'] . '

'
. do_shortcode( $content ) . '

' . esc_attr($alt) . '

';
}


Benim sorum şu: 1. Fonksiyondaki esc_attr($alt) değişkeni resimlerin alternatif yazılarını çekebiliyorken 2. Fonksiyondaki esc_attr($alt) değişkeni bunu yapamıyor. esc_attr($alt) değişkenini 2. Fonksiyonda da etkin hale nasıl getirebilirim?
