I have a page that has a list of items. On the bottom of the page is a "view more" button. When someone clicks this button, the page needs to add more items. The var is $displayedquestions, and the page is coded right now to refresh when the "view more" button is clicked, but we'd like to have it do it live. How can this be done?
Here is code:
<?php
include "db_connect.php";
db_connect();
function tags($tags)
{
$tagarray=explode(",",$tags);
$i=0;
$finished='false';
while($finished=='false') {
if (empty($tagarray[$i])=='true') {
$finished='true';
} else {
$taglist = $taglist . '<a class="commonTagNames" href="">' . $tagarray[$i] . '</a> ';
$i++;
}
}
return $taglist;
}
function formattime($timesince)
{
$strsince=number_format($timesince,0,'','');
$nodecimals=intval($strsince);
if ($nodecimals<1){
return "Less than a minute ago";
} elseif ($nodecimals>=1&&$nodecimals<60) {
return $nodecimals . " min ago";
} elseif ($nodecimals>60&&$nodecimals<1440){
$hourssince=$nodecimals/60;
$hoursnodecimals=number_format($hourssince,0);
return $hoursnodecimals . " hours ago";
} elseif ($nodecimals>1440){
$dayssince=$nodecimals/1440;
$daysnodecimals=number_format($dayssince,0);
return $daysnodecimals . " days ago";
}
}
$submitbutton=$_REQUEST['viewmore'];
$numquestions=intval($_REQUEST['questions']);
if($numquestions!=0) {
$displayedquestions=$numquestions;
} else {
$displayedquestions=10;
}
$sql="SELECT * FROM `Questions` ORDER BY `Questions`.`ID` DESC LIMIT 0, " . $displayedquestions;
$questions=mysql_query($sql);
while($row = mysql_fetch_array($questions))
{
$id = $row['ID'];
$user = $row['userAsking'];
$question = $row['question'];
$tags = $row['tags'];
$timestamp = $row['timestamp'];
$time=strtotime($timestamp);
$secondssince=(date(U)-$time)/60;
$timesince=formattime($secondssince);
$responses=mysql_query("SELECT * FROM `answersToQuestions` WHERE `idOfQuestion`= '$id'");
$comments=mysql_num_rows($responses);
$likes=mysql_query("SELECT * FROM `likesOfQuestions` WHERE `idOfQuestion`= '$id'");
$numlikes=mysql_num_rows($likes);
$userprofileq = mysql_query("SELECT `ID`,`avatar` FROM `Users` WHERE `username` = '$user'");
$userprofileresult = mysql_fetch_row($userprofileq);
$linktoprofile = $userprofileresult[0];
$avatar = $userprofileresult[1];
$taglist=tags($tags);
echo "</li>";
echo '<li class="questionsList" onclick="showUser(' . $id . ')">
