Upload Image in wordpress as attachment

First Of all we need a Form

Then We need a Jquery For Ajax Request


jQuery('body').on('change','#files',function(){
jQuery(this).parents('form').submit();
});


jQuery("form#data").submit(function(event){
event.preventDefault();
var formData = new FormData(jQuery(this)[0]);

jQuery.ajax({
url: ajaxUrl+'?action=cvf_upload_files',
type: 'POST',
data: formData,
async: false,
cache: false,
contentType: false,
processData: false,
success: function (returndata) {
var obj = jQuery.parseJSON(returndata);
UploadedImageContain = obj;
var attachment = [];
if(jQuery("#attachment").length>=1){
var attachmentData = jQuery("#attachment").val();
attachmentData = attachmentData.split(',');

}
if(jQuery("ul#imagesContainerGallery").length>=1){
jQuery("#imagesContainerGallery").remove();
}

jQuery("

").insertAfter(jQuery("#files").parent('form'));
var cList = jQuery('ul#imagesContainerGallery');

jQuery('.ImageSection').find('option').remove();

jQuery('.ImageSection').append(jQuery('', {
value: '',
text :'Select'
}));
jQuery('.ImageSection').append(jQuery('', {
value: 'media',
text :'Media Library'
}));

var index = 1;
jQuery.each(obj,function(k,v){
attachment.push(k);
var li =jQuery('

')
.addClass('ui-menu-item')
.attr('role', 'menuitem')
.appendTo(cList);
var aaa =jQuery('')
.attr('src', v)
.appendTo(li);
jQuery('.ImageSection').append(jQuery('', {
value: k,
text :'Photo'+index
}));
index++;
});

jQuery('.ImageSection').append(jQuery('', {
value: 'NO',
text :'No Photo'
}));

var attachment_new = jQuery('')
.addClass('attachementCustom')
.attr('value',attachment.toString())
.attr('name','attachment')
.attr('id',"attachment")
.attr('type',"hidden")

if(jQuery("#attachment").length>=1){
jQuery("#attachment").remove();
}
jQuery(attachment_new).insertBefore("#files");

}

});

return false;
});


Now next thing would be ajax function


function cvf_upload_files_callback(){

$parent_post_id = isset( $_POST['post_id'] ) ? $_POST['post_id'] : 0;
$valid_formats = array("jpg", "png", "gif", "bmp", "jpeg");
$max_file_size = 1024 * 500;
$max_image_upload = 10;
$wp_upload_dir = wp_upload_dir();
$path = $wp_upload_dir['path'] . '/';
$count = 0;
$attach_id_array = array();
$attachments = get_posts( array(
'post_type' => 'attachment',
'posts_per_page' => -1,
'post_parent' => $parent_post_id,
'exclude' => get_post_thumbnail_id()
) );
if( $_SERVER['REQUEST_METHOD'] == "POST" ){
foreach ( $_FILES['files']['name'] as $f => $name ) {
$extension = pathinfo( $name, PATHINFO_EXTENSION );
$new_filename = $this->cvf_td_generate_random_code( 20 ) . '.' . $extension;
if ( $_FILES['files']['error'][$f] == 4 ) {
continue;
}

if ( $_FILES['files']['error'][$f] == 0 ) {
if ( $_FILES['files']['size'][$f] > $max_file_size ) {
$upload_message[] = "$name is too large!.";
continue;

} elseif( ! in_array( strtolower( $extension ), $valid_formats ) ){
$upload_message[] = "$name is not a valid format";
continue;

} else{
if( move_uploaded_file( $_FILES["files"]["tmp_name"][$f], $path.$new_filename ) ) {

$count++;

$filename = $path.$new_filename;
$filetype = wp_check_filetype( basename( $filename ), null );
$wp_upload_dir = wp_upload_dir();
$attachment = array(
'guid' => $wp_upload_dir['url'] . '/' . basename( $filename ),
'post_mime_type' => $filetype['type'],
'post_title' => preg_replace( '/\.[^.]+$/', '', basename( $filename ) ),
'post_content' => '',
'post_status' => 'inherit'
);
$attach_id = wp_insert_attachment( $attachment, $filename, $parent_post_id );
$attach_id_array[] = $attach_id;

require_once( ABSPATH . 'wp-admin/includes/image.php' );

$attach_data = wp_generate_attachment_metadata( $attach_id, $filename );
wp_update_attachment_metadata( $attach_id, $attach_data );

}
}
}
}

}
if ( isset( $upload_message ) ) :
foreach ( $upload_message as $msg ){
printf( __('

%s

', 'wp-trade'), $msg );
}
endif;

if( $count != 0 ){

//printf( __('

%d files added successfully!

', 'wp-trade'), $count );
}

$attachmentData = array();
if(!empty($attach_id_array)):
for($i=0;$i<count($attach_id_array);$i++){
$attachmentData[$attach_id_array[$i]] = wp_get_attachment_url($attach_id_array[$i]);
}
endif;
echo json_encode($attachmentData);
exit();
}

function cvf_td_generate_random_code($length=10) {

$string = '';
$characters = "23456789ABCDEFHJKLMNPRTVWXYZabcdefghijklmnopqrstuvwxyz";

for ($p = 0; $p < $length; $p++) {
$string .= $characters[mt_rand(0, strlen($characters)-1)];
}
return $string;
}

Email Template

Here the example of email template wordpress function code
$emailTempalte = 'assistant_mail.html';
$template_name = get_bloginfo('template_url').'/custom/emailTemplate/'.$emailTempalte;
$str = file_get_contents($template_name);
$arrayContent= array('!!name!!'=>'Ritesh',
'!!datetime!!' =>'27 aug 2016 Morning',
'!!hospital!!' =>'QFG',
'!!surgeon_name!!'=>'Joshi',
'!!surgeon_address!!'=>'This is testing',
'!!surgeon_number!!'=>'5452144122'
);
foreach($arrayContent as $key=>$vals){
$str = str_replace( $key,$vals,$str);
}
wp_mail($to,$subject,$message,$headers);

Here is the example of html file

<p>Dear !!name!!,</p>
<p>I would like to engage you for the following session </p>
<p>!!datetime!!</p>
<p>!!hospital!!</p>

<p>Please confirm  ASAP by return email, or phone as per the details below </p>

<p>From</p>
<p>!!surgeon_name!!</p>
<p>!!surgeon_number!!</p>

 

Get the author id in author page

$path = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH);
$path = explode('/', $path);
if($path[1] === 'author' && isset($path[2]) && !empty($path[2])) {
$nicename = $path[2];

global $wpdb;
$dblink = $wpdb->get_row("SELECT ID FROM $wpdb->users WHERE user_nicename = '$nicename'");
$author_id = $dblink->ID;
}

table listing display in admin

if( ! class_exists( 'WP_List_Table' ) ) {
require_once( ABSPATH . 'wp-admin/includes/class-wp-list-table.php' );
}

To create a table to your needs you have to derive a class from WP_List_Table:

class My_List_Table extends WP_List_Table {
}

$myListTable = new My__List_Table();

Usually this data would be read from the database:

var $example_data = array(
array('ID' => 1,'title' => 'Share point', 'author' => 'david'),
array('ID' => 2, 'title' => 'Share point new','author' => 'smith'),
array('ID' => 3, 'title' => 'Share point latest', 'author' => 'martin'),
array('ID' => 4, 'title' => 'Share point wet', 'author' => 'johnson'),
array('ID' => 5, 'title' => 'Share point usually', 'author' => 'Markque'),
array('ID' => 6, 'title' => 'Share point test', 'author' => 'Seth Harwood')
);

we have to define some methods and variables:

function get_columns(){
$columns = array(
'title' => 'Title',
'author' => 'Author'
);
return $columns;
}

function prepare_items() {
$columns = $this->get_columns();
$hidden = array();
$sortable = array();
$this->_column_headers = array($columns, $hidden, $sortable);
$this->items = $this->example_data;;
}

that will process any column for which no special method is defined:

function column_default( $item, $column_name ) {
switch( $column_name ) {
case 'booktitle':
case 'author':
case 'isbn':
return $item[ $column_name ];
default:
return print_r( $item, true ) ; //Show the whole array for troubleshooting purposes
}
}
In our example the method will return the title for every column and if the column is not found it displays the content of the $item array for debugging purposes.

These are the essential ingredients to define a custom list table class.

function my_add_menu_items(){
add_menu_page( 'My Plugin List Table', 'My List Table Example', 'activate_plugins', 'my_list_test', 'my_render_list_page' );
}
add_action( 'admin_menu', 'my_add_menu_items' );

function my_render_list_page(){
$myListTable = new My_Example_List_Table();
echo '

My List Table Test

';
$myListTable->prepare_items();
$myListTable->display();
echo '

';
}

}

}
