$_POST not inserting into database - PHP MySQL

Here is my HTML form for adding data into the table:

<div class="TTWForm-container">
<div id="form-title" class="form-title field"><h2>ახალი სტატია</h2></div>
<form enctype="multipart/form-data" action="index.php?link=addart" class="TTWForm ui-sortable-disabled" method="post"> 
<div id="field2-container" class="field f_100 ui-resizable-disabled ui-state-disabled">
<label for="title">სათაური</label>
<input name="title" id="title" required="required" type="text">
</div>
<div id="field10-container" class="field f_100 ui-resizable-disabled ui-state-disabled">
<label for="post">
სტატია
</label>
<textarea rows="15" cols="40" name="post" id="post" required="required"></textarea>
</div>
<div id="form-submit" class="field f_100 clearfix submit">
<input value="დამატება" type="submit" id="submit">
</div>
</form>
</div>

processing

if (isset($_POST['title'])) {$title = $_POST['title'];}
if (isset($_POST['post'])) {$post = $_POST['post'];}

<?php
if (isset($title) && isset($post))
{
/*can add post */
$insert = "INSERT INTO article ('title','post') VALUES ('$title','$post')";
$result = mysqli_query($connect,$insert);

if ($result == 'true') {echo "<p>post is added.</p>";}
else {echo "<p>post is not added.</p>";}
}
else
{
echo "<p>Fill all fields.</p>";
}
?>

After processing it always says that post is not added. Checking database and its true. Cant find the mistake. Please help. Thanks.

Here's a prepared statement for you. 

$link = new MySQLi('localhost','username','password','database');

if(isset($_POST['title'],$_POST['post'])&& $_POST['title'] !="" && $_POST['post'] !=""){
        $title = $_POST['title'];
        $post = $_POST['post'];
        if($query = $link->prepare('INSERT INTO article (title,post) VALUES(?,?)')){
            $query->bind_param('ss',$title,$post);
            $query->execute();
            $query->close();
            echo 'Success!';
        }else{
            echo 'Failure!';
        }
    }else{
        echo 'You missed a field!';
}

so just change:

else
{
echo "<p>post is not added</p>";
}

to:

else
{
echo "<p>MySQL error:".mysqli_error($connect)."</p>";
}

Boolean Comparison

First, check your comparison. mysqli_query returns a boolean true or false, not a string 'true' or 'false.' Instead of:

if ($result == 'true')

use

if ($result == true)

or even:

if ($result)

Debug the Query

Next, check the query itself for errors. As Fred noted, you should mark your column names with back ticks instead of single quotes:

INSERT INTO article (`title`,`post`)

Consider logging the output of mysqli_error, or try echoing your query and run it manually against the database. You may find that they query has a hidden syntax or data error that is not obvious in the code.

Posted Values

Next, check the values that you are fetching from $_POST. Is $_POST['post'] set? Does it have a useful value?

Database Connection

Finally, check the database connection itself. Are you truly connected? Do you have debugging logging or output around the connection attempt?
