I have this function which shows all my articles titles from 'Articles' database.
function show()
{
database();
$sql = "SELECT title FROM `Articles`";
$titleSql = mysql_query( $sql ) or die("Could not select articles:");
$html = '<html><body><div class="container"><h2>Basic List Group</h2><ul class="list-group">';
while ($title = mysql_fetch_array($titleSql)) {
$html .= '<li class="list-group-item">'.$title["title"].'</li>';
}
$html .= '</ul></div></body></html>';
echo $html;
// die("Functie terminata cu succes! :)");
// die(json_encode(array("mesaj" => "Entered data successfully ")));
}
This is the function in javascript.
function show()
{
var n = $('#show').val()
$.post("functions.php", {show:n}).done(function(mesaj){
alert(mesaj);
});
}
PROBLEM: because of the alert(mesaj), it shows the string $html into a pop-up, not on my main window, as I wish!
HOW can I modify my functions so the articles list will show on m window?
you have to give a container id to which it will set the data. Bellow i put it in document.
function show()
{
var n = $('#show').val()
$.post("functions.php", {show:n}).done(function(mesaj){
$(document).html(mesaj);
});
}

I have currently implemented a live search (search as you type) function on text fields. The flow is something like this.
Call a .js file inside the page.
Set the id of the text field to "client-search".
Inside the .js file it is currently listening for on key up events of the "client-search" text field.
If the on key up event is fired, the .js file calls a PHP file that searches the database and returns the output as a list item in an unordered list underneath the "client-search" text field.
This setup currently works but how do implement it in multiple fields inside a single page, since it works using "id" and obviously I can't have multiple IDs in a single page.
HTML:
<div class="input-group">
<input type="text" id="client-search" class="form-control" placeholder="Search for manager...">
<ul class="livesearch" id="client-result" onclick="clickResult()"></ul>
</div>
JS
/* JS File */
// Start Ready
$j(document).ready(function() {
// Icon Click Focus
$j('div.icon').click(function(){
$j('input#client-search').focus();
});
// Live Search
// On Search Submit and Get Results
function search() {
var query_value = $('input#client-search').val();
$j('b#search-string').text(query_value);
if(query_value !== ''){
$j.ajax({
type: "POST",
url: "clientsearch.php",
data: { query: query_value },
cache: false,
success: function(html){
$("ul#client-result").html(html);
}
});
}return false;
}
$j("input#client-search").live("keyup", function(e) {
// Set Timeout
clearTimeout($.data(this, 'timer'));
// Set Search String
var search_string = $(this).val();
// Do Search
if (search_string == '') {
$j("ul#client-result").fadeOut();
}else{
$j("ul#client-result").fadeIn();
$j(this).data('timer', setTimeout(search, 100));
};
});

I have a screen like this:
notifications example
And it deletes the row, but only from the screen. Because if I refresh then it appears back again. I am not sure how to delete it from the actual array.
The array is taken out of a csv file- and I know how to add it back in etc. But what I don't know is deleting rows from the array.
Heres what I have:
// Grabs the csv file (and its existing data) and makes it into an array so the new data can be added to it.
$Notifications = array();
$lines = file('data/AdminNotifications.csv', FILE_IGNORE_NEW_LINES);
foreach ($lines as $key => $value)
{
$Notifications[$key] = str_getcsv($value);
}
echo array2table(array_reverse($Notifications));
// FUNCTION ---------------------------------------------------------------------
//This converts an array to a table
function array2table($array, $recursive = false, $null = ' ')
{
// Sanity check
if (empty($array) || !is_array($array)) {
return false;
}
if (!isset($array[0]) || !is_array($array[0])) {
$array = array($array);
}
// Start the table
$table = "<table>\n";
// The header
$table .= "\t<tr>";
// Take the keys from the first row as the headings
foreach (array_keys($array[0]) as $heading) {
}
$table .= "</tr>\n";
// The body
foreach ($array as $row) {
$table .= "\t<tr>" ;
foreach ($row as $cell) {
$table .= '<td>';
/*
if($cell ==0 && $heading==1){
$cell = $cell.": ";
}
*/
$details = $cell;
// Cast objects
if (is_object($cell)) { $cell = (array) $cell; }
if ($recursive === true && is_array($cell) && !empty($cell)) {
// Recursive mode
$table .= "\n" . array2table($cell, true, true) . "\n";
} else {
$table .= (strlen($cell) > 0) ?
htmlspecialchars((string) $cell) :
$null;
}
$table .= '</td>';
}
$table .= '<td>';
$table .= '<input type="submit" value="Delete" onclick="deleteRow(this)" name="delete"/>';
$table .= '</td>';
$table .= "</tr>\n";
}
$table .= '</table>';
return $table;
}
//If the delete button is pressed, then it does this.
if (isset($_POST['delete'])) {
}
?>
//What happens when it is pressed. (This is javascript)
<script>
function deleteRow(btn) {
var row = btn.parentNode.parentNode;
row.parentNode.removeChild(row);
}
</script>
Any help would be greatly appreciated. I am not too sure whether I can delete a row using javascript? Or in php and java...
Thanks
Php being a server side language will execute only on server. When you are pressing delete button here a javascript function is being called which is actually deleting your row just from client side as it's a client side language that means it actually exist yet on server in that file that's why when you refresh it shows again.
Now you can make an ajax call or place that delete button inside a form to post that request to server to actually delete that.
//If the delete button is pressed, then it does this.
if (isset($_POST['delete'])) {
$arr_index = $_POST['delete']; //you need to pass the row number
unset($array[$arr_index]);
}
we have a form that we can click on a number at the top of the form in order to load the according data, to be more specific i can have 4 inputs in my table in the database and when I click on number 2 which is the id of the data then it loads the data. We did that but now we want to update the clicked data and until now we cant find a way to GET the correct number(id) and place it in the UPDATE statement.
Below is the code of the clicked functions and of the UPDATE statement.
//Education Scripts
$("#updateEdu").click(function () {
$("#idE").css("display", "none");
var r = parseInt($("#idE").val(), 10) + 1;
$("#idE").val(r);
});
$('[data-row-ide]').click(function (e) {
e.preventDefault();
var fileName = 'addCV.php?idEdu='; //"addCV.php" the name of this file in your project, the "?" starts the GET parameters, idWork= sets the key for the GET parameter
var id = $(this).data('row-ide'); // this gets the id that we stored in the link's data attribute
var url = fileName + id; // then we add that id as the value for the "idWork" key
window.location = url; // esentially refresh this page with the id set as a GET parameter and make use of the logic we already have to load the info
});
<?php
$username = $_SESSION["username"];
if(isset($_POST['updateEdu'])){
$parts = parse_url($url);
parse_str($parts['query'], $query);
$id = $query['idEdu'];
$username = $_SESSION['username'];

if (!$result) {

To get the value of an elements attribute in jquery you use the attr() function like so:
$(element).attr('attributeName')
So you should change:
var id = $(this).data('row-ide');
into
var id = $(this).attr('row-ide');
in your function $('[data-row-ide]').click(function (e) {};

$result = null;
$user = JFactory::getUser();
if ($user->guest) {
return false;

$result = $db->loadResult();
if ($db->getErrorNum()) {
JError::raiseWarning( 500, $db->stderr() );
}

Here is something you can do with Ajax, PHP and JQuery. Hope this helps or gives you a start.
See live demo and source code here.
http://purpledesign.in/blog/to-create-a-live-search-like-google/
Create a search box, may be an input field like this.
<input type="text" id="search" autocomplete="off">
Now we need listen to whatever the user types on the text area. For this we will use the jquery live() and the keyup event. On every keyup we have a jquery function “search” that will run a php script.
Suppose we have the html like this. We have an input field and a list to display the results.
<div class="icon"></div>
<input type="text" id="search" autocomplete="off">
<ul id="results"></ul>
We have a Jquery script that will listen to the keyup event on the input field and if it is not empty it will invoke the search() function. The search() function will run the php script and display the result on the same page using AJAX.
Here is the JQuery.
$(document).ready(function() {
// Icon Click Focus
$('div.icon').click(function(){
$('input#search').focus();
});
//Listen for the event
$("input#search").live("keyup", function(e) {
// Set Timeout
clearTimeout($.data(this, 'timer'));
// Set Search String
var search_string = $(this).val();
// Do Search
if (search_string == '') {
$("ul#results").fadeOut();
$('h4#results-text').fadeOut();
}else{
$("ul#results").fadeIn();
$('h4#results-text').fadeIn();
$(this).data('timer', setTimeout(search, 100));
};
});
// Live Search
// On Search Submit and Get Results
function search() {
var query_value = $('input#search').val();
$('b#search-string').html(query_value);
if(query_value !== ''){
$.ajax({
type: "POST",
url: "search_st.php",
data: { query: query_value },
cache: false,
success: function(html){
$("ul#results").html(html);
}
});
}return false;
}
})
;
In the php, shoot a query to the mysql database. The php will return the results that will be put into the html using AJAX. Here the result is put into a html list.
Suppose there is a dummy database containing two tables animals and bird with two similar column names ‘type’ and ‘desc’.
//search.php
// Credentials
$dbhost = "localhost";
$dbname = "live";
$dbuser = "root";
$dbpass = "";
// Connection
global $tutorial_db;
$tutorial_db = new mysqli();
$tutorial_db->connect($dbhost, $dbuser, $dbpass, $dbname);
$tutorial_db->set_charset("utf8");
// Check Connection
if ($tutorial_db->connect_errno) {
printf("Connect failed: %s\n", $tutorial_db->connect_error);
exit();
}
$html = '';
$html .= '<li class="result">';
$html .= '<a target="_blank" href="urlString">';
$html .= '<h3>nameString</h3>';
$html .= '<h4>functionString</h4>';
$html .= '</a>';
$html .= '</li>';
$search_string = preg_replace("/[^A-Za-z0-9]/", " ", $_POST['query']);
$search_string = $tutorial_db->real_escape_string($search_string);
// Check Length More Than One Character
if (strlen($search_string) >= 1 && $search_string !== ' ') {
// Build Query
$query = "SELECT *
FROM animals
WHERE type LIKE '%".$search_string."%'
UNION ALL SELECT *
FROM birf
WHERE type LIKE '%".$search_string."%'"
;
$result = $tutorial_db->query($query);
while($results = $result->fetch_array()) {
$result_array[] = $results;
}
// Check If We Have Results
if (isset($result_array)) {
foreach ($result_array as $result) {
// Format Output Strings And Hightlight Matches
$display_function = preg_replace("/".$search_string."/i", "<b class='highlight'>".$search_string."</b>", $result['desc']);
$display_name = preg_replace("/".$search_string."/i", "<b class='highlight'>".$search_string."</b>", $result['type']);
$display_url = 'https://www.google.com/search?q='.urlencode($result['type']).'&ie=utf-8&oe=utf-8';
// Insert Name
$output = str_replace('nameString', $display_name, $html);
// Insert Function
$output = str_replace('functionString', $display_function, $output);
// Insert URL
$output = str_replace('urlString', $display_url, $output);
// Output
echo($output);
}
}else{
// Format No Results Output
$output = str_replace('urlString', 'javascript:void(0);', $html);
$output = str_replace('nameString', '<b>No Results Found.</b>', $output);
$output = str_replace('functionString', 'Sorry :(', $output);
// Output
echo($output);
}
}
