search results in table with rows limit php - php

Question

I created a web site and i added search option which show search results in table, i want to limit rows number to 5 by page please help me to do that:
i would like also to make search results in random sort for each search operation, not the same results are shown on the first page each search :
this is my search code :
$query = mysql_query("SELECT * FROM table WHERE company LIKE '$company' and activity LIKE '$activity'");
echo "<h3>search results</h3><p>";
echo "<table border='1' align='center' >
<tr>
<th>phone</th>
<th>city</th>
<th>activity</th>
<th>company</th>
</tr>";
while($row = mysql_fetch_array($query))
{
echo "<tr>";
echo "<td>" . $row['phone']. "</td>";
echo "<td>" . $row['city']. "</td>";
echo "<td>" . $row['activity']. "</td>";
echo "<td>" . $row['company']. "</td>";
echo "</tr>";
}
echo "</table>";
$anymatches=mysql_num_rows($result );
if ($anymatches == 0)
{
echo "<h3>sorry no results</h3>";
}
?>
thank you.

Answer 1

Change your query first into
$query = mysqli_query($con,"SELECT * FROM table WHERE company LIKE '%$company%' and activity LIKE '%$activity%' ORDER BY RAND()");
We can use a counter to limit the fetching to 5.
$counter=1;
while($row = mysqli_fetch_array($query)){
if($counter<6){
echo "<td>" . $row['phone']. "</td>";
echo "<td>" . $row['city']. "</td>";
echo "<td>" . $row['activity']. "</td>";
echo "<td>" . $row['company']. "</td>";
}
else {
/* NOTHING TO DO */
}
$counter=$counter+1;
} /* END OF WHILE LOOP */
$anymatches=mysqli_num_rows($result);
if ($anymatches == 0)
{
echo "<h3>sorry no results</h3>";
}
OR you can try this, just changing your query into:
$query = mysqli_query("SELECT * FROM table WHERE company LIKE '%$company%' and activity LIKE '%$activity%' ORDER BY RAND() LIMIT 5");
Please make it clear, if you want to show only 5 results or a pagination with 5 rows per page.
If pagination is what you're looking for:
We should start by storing the data first into a table storage. For example we have a table named search with even just one field, searchfield.
$searchword=mysqli_real_escape_string($con,$_POST['searchword']);
mysqli_query($con,"UPDATE search SET searchfield='$searchword'");
/* this is where you store your search text for later purposes */
And we'll fetch it right away (Don't get me wrong, this is for the pagination purposes)
$selectsearch = "SELECT * FROM search";
$querysearch = mysqli_query($con, $selectsearch) or die(mysqli_error($selectsearch));
while($rows = mysqli_fetch_array($querysearch)){
$search = $rows['searchfield'];
}
$query = "SELECT * FROM table WHERE company LIKE '%$search%' OR activity LIKE '%$search%'"; /* do your query search */
$result = mysqli_query($con, $query);
$count = mysqli_num_rows($result);
$r = mysqli_fetch_row($result);
$numrows = $r[0];
echo '<b> '.$count.' result/s found for "'.$search.'"</b>';
$rowsperpage = 5;
$totalpages = ceil($count / $rowsperpage);
if (isset($_GET['currentpage']) && is_numeric($_GET['currentpage'])) {
$currentpage = (int) $_GET['currentpage'];
} else {
$currentpage = 1;
}
if ($currentpage > $totalpages) {
$currentpage = $totalpages;
}
if ($currentpage < 1) {
$currentpage = 1;
}
$offset = ($currentpage - 1) * $rowsperpage;
$select="SELECT * FROM table WHERE company LIKE '%$search%' OR activity LIKE '%$search%' LIMIT $offset, $rowsperpage"; /* do the query again but with limit */
$result=mysqli_query($con, $select);
/*start of the table*/
{
echo "<table border='1'>
<tr>
<th>phone</th>
<th>city</th>
<th>activity</th>
<th>company</th>
</tr>";
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['city'] . "</td>";
echo "<td>" . $row['activity']. "</td>";
echo "<td>" . $row['company']. "</td>";
echo "</tr>";
}
echo "</table>";
}
echo '<table border="0"><tr><td>';
/* ***** build the pagination links ***** */
$range = 2;
if ($currentpage > 1) {
$prevpage = $currentpage - 1;
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$prevpage'>Previous</a> ";
}
for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {
if (($x > 0) && ($x <= $totalpages)) {
if ($x == $currentpage) {
echo " <font color='#546f3e'><b>$x</b></font> ";
} else {
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x'>$x</a> ";
}
}
}
if ($currentpage != $totalpages) {
$nextpage = $currentpage + 1;
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$nextpage'>Next</a> ";
} // end if
/* ***** end build pagination links ***** */
echo '</td></tr></table>';

Answer 2

You haven't written any pagination code, use MySQL LIMIT , clause.
For ordering randomly, try this:
SELECT * FROM table WHERE company LIKE '$company' and activity LIKE '$activity' ORDER BY RAND()

Answer 3

Start with this. In this you need to pass the page number in URL (Eg yourwebsite/your-php.php?page=0)
$page = $_GET['page'];
$perPage = 5;
$start = $page * $perPage;
$query = mysql_query("SELECT * FROM table WHERE company LIKE '$company' and activity LIKE '$activity' limit " . $start . ',' . $perPage);
echo "<h3>search results</h3><p>";
echo "<table border='1' align='center' >
<tr>
<th>phone</th>
<th>city</th>
<th>activity</th>
<th>company</th>
</tr>";
while($row = mysql_fetch_array($query))
{
echo "<tr>";
echo "<td>" . $row['phone']. "</td>";
echo "<td>" . $row['city']. "</td>";
echo "<td>" . $row['activity']. "</td>";
echo "<td>" . $row['company']. "</td>";
echo "< /tr>";
}
echo "</table>";
$anymatches=mysql_num_rows($result );
if ($anymatches == 0)
{
echo "<h3>sorry no results</h3>";
}
?>
You need to implement pagination in to this by giving link to different page numbers.
I suggest to use some MVC framework rather than having all data retrieval and view in one file.
