Why are my settings not being saved on wordpress admin? - wordpress

Question

I am new to wordpress, and I have build a plugin that just saves settings on the admin menu.
But when I click on the save button it just takes me to the options.php page and doesn't do anything. I have looked over my code a couple of times, and I can't seem to find why its not saving, and just stays at the options.php page.
Any help would be really appreciated!! Thanks
function fflOptionsMenuLink(){
add_options_page("Facebook Footer Link Options", "Facebook Footer Link","manage_options","ffl-options","fflOptionsContent" );
}
function fflOptionsContent(){
$opt = get_option("ffl_settings");
$output = "<div class='wrap'>
<h2>Facebook footer link settings </h2>
<form method='post' action='options.php' id='ffl_settings_group'>";
settings_fields('ffl_settings_group');
$output .= "<table class='form-table'>
<tbody>
<tr>
<th scope='row'><label for='ffl_settings[enable]'>Enable</label> </th>
<td><input name='ffl_settings[enable]' type='checkbox' id='ffl_settings[enable]' value='1' ></td>
</tr>
<tr>
<th scope='row'><label for='ffl_settings[facebook_url]'>Facebook Profile </label> </th>
<td><input name='ffl_settings[facebook_url]' type='text' id='ffl_settings[facebook_url]' value='{$opt["ffl_settings"]}' class='regular-text' ></td>

</tbody>
</table>
<p class='submit'><input type='submit' name='submit' id='submit' class='button button-primary' value='Submit'> </p>
";
$output .= "</form>";
$output.="</div>";
echo $output;
}
add_action("admin_menu","fflOptionsMenuLink");
//Register Settings
function fflRegisterSetting(){
register_setting("ffl_settings_group","ffl_settings");
}
add_action("admin_init","ffl_register_setting");

Few Things...
ISSUE - Your function name for registering settings fflRegisterSetting not ffl_register_setting as in your hook.
ISSUE - You are not outputting submit button by wp function
Reminder - facebook_url field has value wrong $opt["link_color"], but since checkboxes are not ready either so I'll consider this a WIP ;)
So your code should look something like this -
function fflOptionsMenuLink(){
add_options_page("Facebook Footer Link Options", "Facebook Footer Link","manage_options","ffl-options","fflOptionsContent" );
}
function fflOptionsContent(){
$opt = get_option("ffl_settings");
echo "<div class='wrap'>
<h2>Facebook footer link settings </h2>
<form method='post' action='options.php' id='ffl_settings_group'>";
settings_fields('ffl_settings_group');
echo "<table class='form-table'>
<tbody>
<tr>
<th scope='row'><label for='ffl_settings[enable]'>Enable</label> </th>
<td><input name='ffl_settings[enable]' type='checkbox' id='ffl_settings[enable]' value='1' ></td>
</tr>
<tr>
<th scope='row'><label for='ffl_settings[facebook_url]'>Facebook Profile </label> </th>
<td><input name='ffl_settings[facebook_url]' type='text' id='ffl_settings[facebook_url]' value='{$opt["facebook_url"]}' class='regular-text' ></td>
</tr>
<tr>
<th scope='row'><label for='ffl_settings[link_color]'>Enter color or hex value</label> </th>
<td><input name='ffl_settings[link_color]' type='text' id='ffl_settings[link_color]' value='{$opt["link_color"]}' class='regular-text' ></td>
</tr>
<tr>
<th scope='row'><label for='ffl_settings[show_in_feed]'>Show in feed</label> </th>
<td><input name='ffl_settings[show_in_feed]' type='checkbox' id='ffl_settings[show_in_feed]' value='1' ></td>
</tr>
</tbody>
</table>
";
submit_button(); // Get the submit button from this function
echo "</form>";
echo "</div>";
}
add_action("admin_menu","fflOptionsMenuLink");
//Register Settings
function fflRegisterSetting(){
register_setting("ffl_settings_group","ffl_settings");
}
add_action("admin_init","fflRegisterSetting");
