Wordpress Custom Contact Form Not Working - php

Question

I am trying to create a custom contact form page for my Wordpress theme. However on my way to finishing my codes the error message on my page won't show up.
Also, I am running on a localhost computer for testing this custom page and it seems it won't send my message to the ADMIN EMAIL that was set on my Wordpress Installation.
Here's the snippet on my WP Custom Contact Form:
<?php
/* Template Name: Contact Page */
?>
<?php
// Function for email address validation
function isEmail($verify_email) {
return(preg_match("/^[-_.[:alnum:]]+#((([[:alnum:]]|[[:alnum:]][[:alnum:]-]*[[:alnum:]])\.)+(ad|ae|aero|af|ag|ai|al|am|an|ao|aq|ar|arpa|as|at|au|aw|az|ba|bb|bd|be|bf|bg|bh|bi|biz|bj|bm|bn|bo|br|bs|bt|bv|bw|by|bz|ca|cc|cd|cf|cg|ch|ci|ck|cl|cm|cn|co|com|coop|cr|cs|cu|cv|cx|cy|cz|de|dj|dk|dm|do|dz|ec|edu|ee|eg|eh|er|es|et|eu|fi|fj|fk|fm|fo|fr|ga|gb|gd|ge|gf|gh|gi|gl|gm|gn|gov|gp|gq|gr|gs|gt|gu|gw|gy|hk|hm|hn|hr|ht|hu|id|ie|il|in|info|int|io|iq|ir|is|it|jm|jo|jp|ke|kg|kh|ki|km|kn|kp|kr|kw|ky|kz|la|lb|lc|li|lk|lr|ls|lt|lu|lv|ly|ma|mc|md|me|mg|mh|mil|mk|ml|mm|mn|mo|mp|mq|mr|ms|mt|mu|museum|mv|mw|mx|my|mz|na|name|nc|ne|net|nf|ng|ni|nl|no|np|nr|nt|nu|nz|om|org|pa|pe|pf|pg|ph|pk|pl|pm|pn|pr|pro|ps|pt|pw|py|qa|re|ro|ru|rw|sa|sb|sc|sd|se|sg|sh|si|sj|sk|sl|sm|sn|so|sr|st|su|sv|sy|sz|tc|td|tf|tg|th|tj|tk|tm|tn|to|tp|tr|tt|tv|tw|tz|ua|ug|uk|um|us|uy|uz|va|vc|ve|vg|vi|vn|vu|wf|ws|ye|yt|yu|za|zm|zw)$|(([0-9][0-9]?|[0-1][0-9][0-9]|[2][0-4][0-9]|[2][5][0-5])\.){3}([0-9][0-9]?|[0-1][0-9][0-9]|[2][0-4][0-9]|[2][5][0-5]))$/i",$verify_email));

Any idea? or Is there a way you can correct my code if you see some errors?

Answer 1

To get you started
Make sure WP_DEBUG is set to true on your wp-config.php file.
You can get the last errors from mail() (answered here)
Use wordpress' functions if available, in this case wp_mail is at your disposal.
There are wordpress plugins such as gravity forms or contact form 7 which can accomplish the task.
Use filters and actions.

Answer 2

If you would like to get the admin email address, you have to do it with:
$bloginfo = get_bloginfo( 'admin_email' );
get_option('admin_email') is only works when you save anything to that in the Theme Setup, probably it is empty now.
By the way, you can find many of professional, ready to use solution, like WordPress Contact Form Slider
