PHP Search form is testing only last row of the database - php

Question

I am trying to create a search facility for a website. the website contains text posts so the database has a table post_record with field post_id, post_title, post_href and post_content.
now the working is when a user enters any search keyword in search field, that keyword is being tested against all the post titles and post contents and where it matches it should return all those rows. Following is the code for it. the issue is its returning only the last row of the databse.
<table class="s_table">
<?php
require_once'config.php';
if(isset($_POST['search_btn']))
{
$mes = " ";
$search_key =" ";
$search_key = ($_POST['search_field']);
try
{
if(empty($search_key) && $search_key != " ")
{
echo $mes = "Enter the keyword you want to search.";
}
else
{
$result = $conn->prepare("SELECT * FROM post_record WHERE post_title LIKE '%".$search_key."%' OR post_content LIKE '%".$search_key."%'");
$result->execute();
$count=$result->rowCount();
$datas = $result->fetchAll();
if(!$count)
{
echo $mes = "No Result found. Try another keyword for search.";
}
else
{
foreach ($datas as $data)
{
echo "
<tr><td><b><u><a href='".$data['post_href']."'>".$data['post_title']."</a></b></u></td></tr><br>
<tr><td class='s_cont'>".$data['post_content']."</tr></td><br><br>";
}
}
}
}
catch(PDOException $e)
{
$mes = "Something Went Wrong! try again";
header("location:index.php");
}
}
$conn = null;
?>
Everything is working fine except the thing that it is displaying only last row of the database.
Right now database has 3 posts and for testing purpose i tried a keyword that i know is common in all the post contents but its not working. only last row the database is being fetched and tested.

Answer 1

if(empty($search_key) && $search_key != " ") this condition is wrong
Both are different things which wont get true ever.
you are testing if its empty and then u r testing if its not empty
Both in same if condition

Answer 2

I usually use procedual functions but I encounter a problem like this with the mysqi_fetch_array(), so your problem might be that fetchAll() is moving the cursor to the last record. Try to remove that function or use mysql_data_seek($datas , 0) before the foreach() .
