PHP and AJAX onclick redirection - php

Question

I am using Ajax to populate a drop down menu from the database, my question is how do I onclick redirect it to a page along with the CARD_ID i got back from the database?
right now when I click on it it's displaying the card name in the search bar which is part of what I want but now I need the other half the redirection. How can I achieve this?
<?php
$mysqli = mysqli_connect('localhost', 'root', '', 'draftdb');
if(mysqli_connect_errno())
{
echo "Connection Failed: " . mysqli_connect_errno();
exit();
}
$str = $_GET['content'];
if(strlen($str))
{
$sel = mysqli_query($mysqli, "select CARD_NAME, CARD_ID,CARD_TYPE from cards where CARD_NAME like '".trim($str)."%'");
if(mysqli_num_rows($sel))
{
echo "<table border =\"0\" width=\"100%\">\n";
if(mysqli_num_rows($sel))
{
echo "<script language=\"javascript\">box('1');</script>";
while($row = mysqli_fetch_array($sel))
{
$card_info = str_ireplace($str,"<b>".$str."</b>",($row['CARD_NAME']));
$card_type = str_ireplace($str,"<b>".$str."</b>",($row['CARD_TYPE']));
echo "<tr id=\"word".$row['CARD_ID']."\" onmouseover=\"highlight(1,'".$row['CARD_ID']."');\" onmouseout=\"highlight(0,'".$row['CARD_ID']."');\" onClick=\"display('".$row['CARD_NAME']."');\" >\n<td>".$card_info." ".$card_type."</td>\n</tr>\n";
}
}
echo "</table>";
}
}
else
{
echo "<script language=\"javascript\">box('0');</script>";
}
?>
the javascript.
subject_id = '';
function handleHttpResponse() {
if (http.readyState == 4) {
if (subject_id != '') {
document.getElementById(subject_id).innerHTML = http.responseText;
}
}
}
function getHTTPObject() {
var xmlhttp;
/*#cc_on
#if (#_jscript_version >= 5)
try {
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
} catch (E) {
xmlhttp = false;
}
}
#else
xmlhttp = false;
#end #*/
if (!xmlhttp && typeof XMLHttpRequest != 'undefined') {
try {
xmlhttp = new XMLHttpRequest();
} catch (e) {
xmlhttp = false;
}
}
return xmlhttp;
}
var http = getHTTPObject(); // We create the HTTP Object
function getScriptPage(div_id,content_id)
{
subject_id = div_id;
content = document.getElementById(content_id).value;
http.open("GET", "script_page.php?content=" + escape(content), true);
http.onreadystatechange = handleHttpResponse;
http.send(null);
if(content.length>0)
box('1');
else
box('0');
}
function highlight(action,id)
{
if(action)
document.getElementById('word'+id).bgColor = "#C2B8F5";
else
document.getElementById('word'+id).bgColor = "#F8F8F8";
}
function display(word)
{
document.getElementById('text_content').value = word;
document.getElementById('box').style.display = 'none';
document.getElementById('text_content').focus();
}
function box(act)
{
if(act=='0')
{
document.getElementById('box').style.display = 'none';
}
else
document.getElementById('box').style.display = 'block';
}
the html
<div class="ajax-div">
<div class="searchbar">
<input type="text" onKeyUp="getScriptPage('box','text_content')" id="text_content">
</div>
<div id="box"></div>
</div>

Answer 1

I'm not sure what you are trying to do, but it seems you want something like this:
1- Change the way you display your rows so that the ID gets sent to your function as well:
echo "<tr id=\"word".$row['CARD_ID']."\" onmouseover=\"highlight(1,'".$row['CARD_ID']."');\" onmouseout=\"highlight(0,'".$row['CARD_ID']."');\"
onClick=\"display('".$row['CARD_NAME']."', " . $row['CARD_ID'] . ");\" >\n<td>".$card_info." ".$card_type."</td>\n</tr>\n";
^^^^^^^^^^^^^^^^^^^^^^^^^
2- Change your display function to redirect
function display(word, id)
{
// document.getElementById('text_content').value = word;
// document.getElementById('box').style.display = 'none';
// document.getElementById('text_content').focus();
window.location.href = "some_page.php?card_id=" + id;
}
I have commented out the original lines because there doesn't seem much point in doing stuff on a page you are leaving anyway. You could also completely remove the word parameter if this is the solution you are looking for.
