Adding comment to specific post using id with Angularjs and PHP - php

Question

I am new to Angular and am struggling to add a comment to a specific post that is being displayed from a database.
Under the post I have a hidden comment area that shows when pressing the button.
I then want to be able to add the comment to the post the comment area is attached too.
It seems like it is not getting the id but I can't find how to solve it.
It is doing the show/hide, and I am getting the "data inserted" in the console log so I'm guessing the problem is with the PHP?
Angular code
app.controller('meetings', function($scope, $http) {
$scope.meetings_insertdata = function() {
$http.post ("meetings_insert.php",{'meetings_commentdate':$scope.meetings_commentdate,'meetings_comment':$scope.meetings_comment})
window.location.reload();
console.log("data inserted");
};
});
app.controller('show_hide', function ($scope) {
$scope.Hidden = true;
$scope.ShowHide = function () {
$scope.Hidden = $scope.Hidden ? false : true;
}
});
meetings_insert.php
<?php
$data = json_decode(file_get_contents("php://input"));
$meetings_comment = $data->meetings_comment;
$meetings_commentdate = date('Y-m-d H:i:s');
$meetings_entry = $_GET['id'];
mysql_connect("localhost","user","password");
mysql_select_db("mdb_rh316");
mysql_query("UPDATE project_meetings SET (meetings_comment, meetings_commentdate) = ('$meetings_comment','$meetings_commentdate') WHERE meetings_entry = '$meetings_entry'");
?>
HTML code
<div class="entrybox" ng-controller="meetings">
<?php
mysql_connect("localhost","user","password");
mysql_select_db("mdb_rh316");
$result = mysql_query("SELECT * FROM project_meetings ORDER BY meetings_date DESC");
while ($row = mysql_fetch_array($result))
{
echo "<table>";
echo "<tr><td>" ?>Added: <? echo $row['meetings_date'] . $row['meetings_entry'] . "<br/>" . $row['meetings_content']."</td></tr>";
echo "<tr><td>" ?><br/><span class="emp">Comment: <?
echo $row['meetings_commentdate']."<br/>" . $row['meetings_comment']."</td></tr>";
echo "<tr><td>"?></span>
<div ng-controller="show_hide">
<input type="button" class="previous_add" value="Add comment" ng-click="ShowHide()" />
<br />
<br />
<div ng-hide = "Hidden">
<form method="post" action="meetings_insert.php?id=<? echo $row['$meetings_entry']?>">
<textarea class="textarea" placeholder="Add your comment here.." type="text" ng-model="meetings_comment" name="meetings_comment"></textarea><br/>
<input type="button" class="button" value= "Add" ng-click="meetings_insertdata()"/>
</form>
</div>
</div>
</td></tr><br/><?;
}
echo "</table>";
?>
</div>

Pass 'id' into the meetings_insertdata function:
<form method="post" action="">
<textarea class="textarea" placeholder="Add your comment here.." type="text" ng-model="meetings_comment" name="meetings_comment"></textarea>
<br/>
<input type="button" class="button" value="Add" ng-click="meetings_insertdata(<? echo $row['$meetings_entry']?>)" />
</form>
Receive it in the AngularJS function below:
app.controller('meetings', function($scope, $http) {
$scope.meetings_insertdata = function(id) {
$http.post("meetings_insert.php", {
'meetings_commentdate': $scope.meetings_commentdate,
'meetings_comment': $scope.meetings_comment,
'meetings_event': id
})
window.location.reload();
console.log("data inserted");
};
});
Then, pick up 'id' from the posted value ($data->meetings_event)
$data = json_decode(file_get_contents("php://input"));
$meetings_comment = $data->meetings_comment;
$meetings_commentdate = date('Y-m-d H:i:s');
$meetings_entry = $data->meetings_event;
