Getting first image instead of featured image

  • First of all, thanks for this plugin.

    It’s almost perfect for me except I want to add the first image in the content when there’s no featured image.
    For this I added following code in the functions.php

    //function to call first uploaded image in functions file
function main_image() {
$files = get_children('post_parent='.get_the_ID().'&post_type=attachment
&post_mime_type=image&order=desc');
  if($files) :
    $keys = array_reverse(array_keys($files));
    $j=0;
    $num = $keys[$j];
    $image=wp_get_attachment_image($num, 'large', true);
    $imagepieces = explode('"', $image);
    $imagepath = $imagepieces[1];
    $main=wp_get_attachment_url($num);
		$template=get_template_directory();
		$the_title=get_the_title();
    print "<img src='$main' alt='$the_title' class='frame' />";
  endif;
}

    and then I can retrieve the first image in the content with this

    <?php if (  (function_exists('has_post_thumbnail')) && (has_post_thumbnail())  ) {
  echo get_the_post_thumbnail($post->ID);
} else {
   echo main_image();
} ?>

    I tried to add this to your plugin and I messed a lot between lines 744 -> 749 but couldn’t integrate this piece of code in there.

    I’ll be happy if you can help me out with this.

    Thanks

    Hi!

    You should adjust your function to receive the post ID as a parameter

    function main_image( $post_ID = 0 ) {
	/** If the post ID is not specified, let's get the files for is the current object */
	if ( empty( $post_ID ) ) {
		$files = get_children( 'post_parent=' . get_theID() . '&post_type=attachment&post_mime_type=image&order=desc' );
	} else {
		$files = get_children( 'post_parent=' . (int) $post_ID . '&post_type=attachment&post_mime_type=image&order=desc' );
	}
	if ( $files ) :
		$keys = array_reverse( array_keys( $files ) );
		$j=0;
		$num = $keys[$j];
		$image=wp_get_attachment_image( $num, 'large', true );
		$imagepieces = explode( '"', $image );
		$imagepath = $imagepieces[1];
		$main = wp_get_attachment_url( $num );
		$template = get_template_directory();
		$the_title = get_the_title();
		print '<img src="' . $main . '" alt="' . $the_title .'" class="frame" />';
	endif;
}

    Then, send the parameter also in the lines you changed in my plugin

    <?php if ( ( function_exists( 'has_post_thumbnail' ) ) && ( has_post_thumbnail() ) ) {
  echo get_the_post_thumbnail( $post->ID );
} else {
   echo main_image( $post->ID );
} ?>

    Let me know if this helps

    Honestly couldnt figure out how to display it in the $tile

    if ( ( function_exists( 'has_post_thumbnail' ) ) && ( has_post_thumbnail() ) ) {
				if ( ! empty( $args['mainimage'] ) ) {
					$mainimage = wp_get_attachment_image_src( main_image( intval( $post->ID ) ), $args['mainimage'] );
					if ( ! empty( $mainimage[0] ) ) {
						$tile = str_replace( '[mainimage]', '<img src="' . esc_url( $mainimage[0] ) . '" />', $tile );
					} else {
						$tile = str_replace( '[mainimage]', '', $tile );
					}
				} else {
					$tile = str_replace( '[mainimage]', '', $tile );
				}
			}
