Show all rows on PHP/sql - php

Question

I'm doing a small app. The thing is that when I'm running it, it will only show 300 rows when I should have around 2000 that I inserted for the test. It just doesn't shows them. It shows 312 rows, and not the rest.
Here is the code:
<!-- page content -->
<div class="right_col" role="main">
<div class="page-title">
<div class="title_left">
<h3>Raw Inventory</h3>
</div>
<div class="title_right">
<div class="col-md-5 col-sm-5 col-xs-12 form-group pull-right top_search">
<div class="input-group">
<input type="text" class="form-control" placeholder="Search for...">
<span class="input-group-btn">
<button class="btn btn-default" type="button">Go!</button>
</span>
</div>
</div>
</div>
</div>
<div class="row">
<div class="col-md-12 col-sm-12 col-xs-12">
<div class="x_panel">
<div class="x_title">
<h2>Assets List</h2>
<ul class="nav navbar-right panel_toolbox">
<li><a class="collapse-link"><i class="fa fa-chevron-up"></i></a>
</li>
<li><a class="close-link"><i class="fa fa-close"></i></a>
</li>
</ul>
<div class="clearfix"></div>
</div>
<div class="x_content">
<div class="wrapper">
<div class="container-fluid">
<div class="row">
<div class="col-md-12">
<div class="page-header clearfix">
<h2 class="pull-left"></h2>
Add a new Asset
</div>
<?php
// Include config file
require_once 'config.php';
// Attempt select query execution
$sql = "SELECT * FROM t_assets";
if($result = mysqli_query($db, $sql)){
if(mysqli_num_rows($result) > 0){
echo "<table class='table table-bordered table-striped'>";
echo "<thead>";
echo "<tr>";
echo "<th>Asset</th>";
echo "<th>Model</th>";
echo "<th>Status</th>";
echo "<th>Location</th>";
echo "<th>Action</th>";
echo "</tr>";
echo "</thead>";
echo "<tbody>";
while($row = mysqli_fetch_array($result)){
echo "<tr>";
echo "<td>" . ucfirst ($row['a_asset']) . "</td>";
echo "<td>" . $row['a_model'] . "</td>";
echo "<td>" . ucfirst($row['a_status']) . "</td>";
echo "<td>" . ucfirst($row['a_location']) . "</td>";
echo "<td>";
echo "<a href='read.php?id=". $row['a_asset'] ."' title='View Record' data-toggle='tooltip'><span class='glyphicon glyphicon-eye-open'></span></a>  ";
echo "<a href='update.php?id=". $row['a_asset'] ."' title='Update Record' data-toggle='tooltip'><span class='glyphicon glyphicon-pencil'></span></a>  ";
echo "<a href='delete.php?id=". $row['a_asset'] ."' title='Delete Record' data-toggle='tooltip'><span class='glyphicon glyphicon-trash'></span></a>";
echo "</td>";
echo "</tr>";
}
echo "</tbody>";
echo "</table>";
// Free result set
mysqli_free_result($result);
} else{
echo "<p class='lead'><em>No records were found.</em></p>";
}
} else{
echo "ERROR: Could not able to execute $sql. " . mysqli_error($db);
}
// Close connection
mysqli_close($db);
?>
</div>
</div>
</div>
</div>
</body>
</html> </div>
</div>
</div>
</div>
</div>
</div>
Any idea what I can do about this?
This is really my only problem, and I just need to add more text right now.
Or well, if you guys want to give me tips to make a global search function that would also be nice. Like, being able to search for information on all columns. Though I'm quite sure that It's not that hard.
I wonder... I need to investigate how to sort the results by name or creation date too.
Thanks, everyone!
