php_fetch redirection failed? - php

Question

I'm very new to php. when I try to register a form through php. the data
s are submitted to database but the redirection to a particular page is failed.
I have my login form named as index.php in root directory. and my registration form in second level directory. and my registration form control is in first level of directory. I used php_fetch for url sanitize. Here is my folder structure -
root->inc(folder)
->index.php
inc(folder)->pages(folder)
->registration.con.php
pages(folder)->registrster.php
here is my form controls
<form class="js-validation-register form-horizontal push-50-t push-50" action="<?php echo esc_url($_SERVER['PHP_SELF']); ?>" method="post" name="registration_form">
<div class="form-group">
<div class="col-xs-12">
<div class="form-material form-material-success">
<input class="form-control" type="text" id="username" name="username" placeholder="Please enter a username">
<label for="username">Username</label>
</div>
</div>
</div>
<div class="form-group">
<div class="col-xs-12">
<div class="form-material form-material-success">
<input class="form-control" type="email" id="email" name="email" placeholder="Please provide your email">

</div>
<div class="form-group">
<div class="col-xs-12">
<div class="form-material form-material-success">
<input class="form-control" type="password" id="password" name="password" placeholder="Choose a strong password..">

</div>
</div>
</div>
<div class="form-group">

</div>
<div class="form-group">
<div class="col-xs-12">
<label class="css-input switch switch-sm switch-success">
<input type="checkbox" id="register-terms" name="register-terms"><span></span> I agree with terms & conditions
</label>
</div>
</div>
<div class="form-group">
<div class="col-xs-12 col-sm-6 col-md-5">
<input class="btn btn-block btn-success" type="button"

onclick="return regformhash(this.form,
this.form.username,
this.form.email,
this.form.password,
this.form.confirmpwd);" />
</div>
</div>
</form>
here is my php_fwtch function
function esc_url($url) {
if ('' == $url) {
return $url;
}
$url = preg_replace('|[^a-z0-9-~+_.?#=!&;,/:%#$\|*\'()\\x80-\\xff]|i', '', $url);
$strip = array('%0d', '%0a', '%0D', '%0A');
$url = (string) $url;
$count = 1;
while ($count) {
$url = str_replace($strip, '', $url, $count);
}
$url = str_replace(';//', '://', $url);
$url = htmlentities($url);
$url = str_replace('&', '&', $url);
$url = str_replace("'", ''', $url);
if ($url[0] !== '/') {
// We're only interested in relative links from $_SERVER['PHP_SELF']
return '';
} else {
return $url;
}
}
