How to retrieve MySQL database data using a php search bar - php

Question

I have created a search bar using PHP and I want to retrieve the data I have in my MySQL database.
My code is as follows:
<?php
$button = $_GET ['submit'];
$search = $_GET ['search'];
if(!$button)
echo "You searched for '<b>$search</b>' <hr size='1'</br>";
$con=mysqli_connect("localhost", "root", "root", "PM_DB");
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$search_exploded = explode (" ", $search);
foreach($search_exploded as $search_each)
{
$x++;
if($x==1)
$construct .="keywords LIKE '%$search_each%'";
else
$construct .="AND keywords LIKE '%$search_each%'";
}
$construct ="SELECT * FROM Leads WHERE $construct";
$run = mysqli_query($construct);
$foundnum = mysqli_num_rows($run);
if ($foundnum==0)
echo "There are no results for <b>'$search'</b>. Please check your spelling.";
else
{
echo "$foundnum results found !<p>";
while($runrows = mysqli_fetch_assoc($run))
{
$Company = $runrows['Clients'];
echo "<a href='$Company'><b>Company</b></a><br>";
}
}
?>
Every time I click search it only returns the error message. What am I missing out? Any suggestions will be highly appreciated! Thanks - Tijger.

Answer 1

Try this code
$search_exploded = explode(" ", $search);
$construct = "SELECT * FROM Leads WHERE keywords LIKE ";
$construct .= "'%".implode("%' OR '%", $search_exploded)."%'";
$run = mysqli_query($construct);

Answer 2

As I requested the code from OP
I commented the two lines which were causing error for him
He was executing the right query and then the wrong query again ... that is why getting no results returned.
<?php
$button = $_GET ['submit'];
$search = $_GET ['search'];
if (!$button)
echo "You searched for '<b>$Search</b>' <hr size='1'</br>";
$con = mysqli_connect("localhost", "root", "root", "PM_DB");
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$search_exploded = explode(" ", $search);
$construct = "SELECT * FROM Leads WHERE keywords LIKE ";
$construct .= "'%" . implode("%' OR '%", $search_exploded) . "%'";
$run = mysqli_query($construct) or die(mysql_error());
// Why thisssssssssssssssssss??????????? OMG
//$construct = "SELECT * FROM Leads WHERE $construct";
//$run = mysqli_query($construct);
$foundnum = mysqli_num_rows($run) or die(mysql_error());
if ($foundnum == 0)
echo "There are no results for <b>'$search'</b>. Please check your spelling.";
else {
echo "$foundnum results found !<p>";
while ($runrows = mysqli_fetch_assoc($run)) {
$Company = $runrows['Clients'];
echo "<a href='$Company'><b>Company</b></a><br>";
}
}
?>
