My question is over creating a self-processing form that inserts to a database and then refreshes, incrementing arrays to change relevant info in the form. (though if there is an easier or better way to do this, I'm all ears).
So site is essentially a digital equivalent to an exercise journal. The user selects a template name from a select menu, then it queries the database for that template, then returns the result to a variable. The exercise names and number of sets per exercise (which will be used to calculate maximum number of form refreshes) are passed into their own respective arrays: $exerciseName[]; and $setNum[];
This is a screenshot of the form.
My question is how to go about setting up the logic so that I can keep submitting until the last set of the last exercise, where upon the final submission, would take to a different page.
I am using mysql_ functions, which I know is frowned upon, but it is for school which uses PHP 5.2.12 and that is what my teammates know so I have no other options. I haven't tried to prevent mysql injections because I don't intend to take this version online.
Here is the code for selecting type of workout and workout template:

You can use PHP_SELF (eg <?php echo htmlentities ($ _ SERVER ['PHP_SELF']); ?>) In the action of the form. See this article which explains why we need htmlentities. This PHP_SELF variable contains the path to the current script.
All the logic you can place where you have, before the template, where you should check the following:
Did happen a page submit?
If yes, check for errors with submitted data.
If there are no errors treats and saves the information. If there are send an array with errors for the template.
If not, nothing to do.
Thus, when there is submission of the form everything will always be submitted on the same page.

I'm trying to get 3 values to insert from the table, 'parents' to the table, 'children' in MySql. One of the values, entitled "code" inserts perfectly. However, I can't get the other two, "email" and "website" to insert. When I add them to the javascript code, it just inserts "code" 3 times. Can someone help me please? Here's the code that inserts just the 'code' field from parents to children:
$("a#reply").one("click", function() {
var comCode = $(this).attr("name");
var parent = $(this).parent();
parent.append("<br /><form id='reply-form-toggle' action='' method='post'><input type='text' name='user' placeholder='Your Name *' required='required' required><br><textarea class='form-text' name='new-reply' id='new-reply' placeholder='Your Reply' required='required'></textarea><input type='hidden' name='code' value='"+comCode+"' /><span style='float: right;'><a onclick='hideReplyForm();'>Cancel</a> <input type='submit' class='form-submit' id='form-reply' name='new_reply' value='Reply' /></span></form>");
});

It always come out with one polls only. Although i have different polls saved in database. It always can show the first id of the database.
<form action="" method="post" name="pollFrm">
<?php
//include and initialize Poll class
include 'Poll.class.php';
$poll = new Poll;
//get poll and options data
$pollResult= $poll->getPolls();
?>
<div class="pollContent">
<?php echo !empty($statusMsg)?'<p class="stmsg">'.$statusMsg.'</p>':''; ?>
<form action="" method="post" name="pollFrm">
<h3><?php echo $pollResult['poll']['subject']; ?></h3>
<ul>
<?php foreach($pollResult['name'] as $opt){
echo '<li><input type="radio" name="voteOpt" value="'.$opt['id'].'" >'.$opt['name'].'</li>';
} ?>
</ul>
<input type="hidden" name="pollID" value="<?php echo $pollResult['poll']['id']; ?>">
<input type="submit" name="voteSubmit" class="button" value="Vote">

This is the function to get polls. I have try to delete the single. but it cant works.

$pollData = array();
$sql = "SELECT * FROM ".$this->pollTbl." WHERE status = '1' ORDER BY created DESC";
$pollResult = $this->getQuery($sql, $pollType);

if($pollType == 'single'){
$pollData['poll'] = $pollResult;
$sql2 = "SELECT * FROM ".$this->optTbl." WHERE poll_id = ".$pollResult['id']." AND status = '1'";
$optionResult = $this->getQuery($sql2);
$pollData['name'] = $optionResult;
}else{
$i = 0;
foreach($pollResult as $prow){
$pollData[$i]['poll'] = $prow;
$sql2 = "SELECT * FROM ".$this->optTbl." WHERE poll_id = ".$prow['id']." AND status = '1'";
$optionResult = $this->getQuery($sql2);
$pollData[$i]['name'] = $optionResult;
}
}
}
return !empty($pollData)?$pollData:false;
}
/*
* Runs query to the database
* #param string SQL
* #param string count, single, all
*/
private function getQuery($sql,$returnType = ''){
$result = $this->db->query($sql);
if($result){
switch($returnType){
case 'count':
$data = $result->num_rows;
break;
case 'single':
$data = $result->fetch_assoc();
break;
default:
if($result->num_rows > 0){
while($row = $result->fetch_assoc()){
$data[] = $row;
}
}
}
return !empty($data)?$data:false;
}
Your function getPolls has a default parameter of $pollType = 'single' passing nothing through to the function will result it resolving to the default of 'single'.
As that parameter is being passed down to getQuery function it's always only going to get one. I would suggest removing the default parameter entirely and changing the method to:
public function getPolls($pollType){
I have a dynamic search which uses jQuery and a PHP search file to dynamically show the results below. I just changed my log in scripts and sessions; now i am having issues with a search bar that searches through the members in a DB. When I was going through the testing I see that on each keyUp the jQuery function runs properly but there is some sort of issue inside of my search.php file. It seems like there is no $userCount or $userCount = 0 because it will display "There Were No Search Results"which only happens when it equals $userCount== 0
Here are the parts of my index.php
<script type="text/javascript">
function searchUserQ(){
var searchTxt = $("input[name='userSearch']").val();
if (searchTxt == '') {
// $.post("includes/search.php", {searchVal:searchTxt},
// function(output){
// $("#userResults").html(output);
// });
}else{
$.post("includes/search.php", {searchVal:searchTxt},
function(output){
$("#userResults").html(output);
});
console.log(output);
}
}
</script>
<form class="editUser" action="index.php" method="post">
<h1>Search For Employee</h1>
<input type="text" name="userSearch" id="userSearch" placeholder="Search For Employee By First Or Last Name | Press Space To View All Employees" onkeyup="searchUserQ();" />
<submit type="submit" />
div id="userResults">
</div>
</form>
and here is my search.php file
<?php
// this file connects to the database
include("connect.inc.php");
if(isset($_POST['searchVal'])){
// turn that the user searched into a varible
$searchQ = $_POST['searchVal'];
// delete any symbols for security
$searchQ = preg_replace("#[^0-9a-z]#i", "", $searchQ);
$output = "";
// Search through these columns inside the main database
$userSearchQuery = mysql_query("SELECT * FROM dealerEmployees WHERE
firstName LIKE '%$searchQ%' or
lastName LIKE '%$searchQ%'
");
// count the number of results
$userCount = mysql_num_rows($userSearchQuery);
if($userCount == 0){
// $output = "There Were No Search Results";
}else{
while($row = mysql_fetch_array($userSearchQuery)){
// define dynamic varibles for each loop iteration
$id = $row['id'];
$firstName = $row['firstName'];
$lastName = $row['lastName'];
$address = $row['address'];
$phone = $row['phone'];
$email = $row['email'];
$passwordQ = $row['password'];
$permission = $row['permission'];
$photo = "images/" . $row['profilePhoto'];
$output .= "<li><div class='employeeSearch' style=\"background: url('$photo'); width: 75px; height: 75px\"></div><h6>" . $firstName . "</h6>" . " " . "<h6>" . $lastName . "</h6><a href='#' class='employee' data-firstName='$firstName' data-lastName='$lastName' data-address='$address' data-phone='$phone' data-email='$email' data-password='$passwordQ' data-permission='$permission' data-id='$id'>Select Employee</a></li>";
}
}
}
echo $output;
Any suggestions why this is happening?
The reason for the error in the title is that you have console.log(output) outside the callback function. This has two problems: First, the variable output is not in scope; second, it runs immediately, not after the AJAX call returns. Move it into the callback:
function searchUserQ(){
var searchTxt = $("input[name='userSearch']").val();
if (searchTxt != '') {
$.post("includes/search.php", {searchVal:searchTxt},
function(output){
console.log(output);
$("#userResults").html(output);
});
}
}
I have searched endlessly for an answer but have found none. I am trying to get the id of a clicked item. The item that I am clicking is from mysql database and has been displayed through a for loop. When the item is clicked I am taken to another page. In this page I want to utilize the id from the clicked item to get other information from that row in mysql database; this much I can do. The problem is getting the id from the clicked item and sending it.
This is the most recent way that I tried:
First I displayed the items from mysql.
<?php
$query = "SELECT `video` FROM `challenge_name` ORDER BY `id`";
$result = mysql_query($query);
if($result = mysql_query($query))
{
for($i = 0; $i < mysql_num_rows($result); $i++)
{
$id = $i;
$code = "<div id=\"challenge_preview\"><h7 class=\"challenge_preview_item\"
id=\"challenge_preview_name\"></h7><a href=\"challengeprofile.php\">
<video
class=\"challenge_preview_item\" id=\"challenge_video\"
src=\"".mysql_result($result, $i)."\"></video></a></div>";
echo $code;
}
}
else
{
die('Couldn\'t connect'. mysql_error());
}
?>
Than I put the id in a hidden form so that I could attempt to POST it to the other page:
<form action="<?php echo $current_file; ?>" method="POST">
<input type="hidden" name="id" value="14">
</form>
On the script.php file that is included in both pages, I put
$(#challenge_video).click(function(){ <?php $id = $_POST['id']; ?> ;});
And on the page that the id is being posted to I put
<?php
include 'script.php';
echo getChallengeData('name', 'id', $id)
?>
Please help, Thank you
These are the edits
<div id='challenge_previews'>
<?php
$query = "SELECT `video` FROM `challenge_name` ORDER BY `id`";
$result = mysql_query($query);
if($result = mysql_query($query))
{
for($i = 0; $i < mysql_num_rows($result); $i++)
{
$id = $i;
echo "<div id=\"challenge_preview\"><video class=\"challenge_preview_item challenge_video\" src=\"".mysql_result($result, $i)."\"></video></div>";
}
}
else
{
die('Couldn\'t connect'. mysql_error());
}
?>
<form action="<?php echo $current_file; ?>" method="GET">
<input type="hidden" name="id" value="14">
</form>
</div>
This is the code for page 2
<h1 id="challenge_profile_name">
<?php
$id = substr(base64_decode($_GET['id']),6);
echo getChallengeData('name', 'id', $id);
?>
</h1>
This is the code for the getChallengeData method in the core.inc.php
function getChallengeData($field1, $field2, $field3)
{
$query = "SELECT `$field1` FROM `challenge_name` WHERE `$field2` = '$field3'";
if($query_run = mysql_query($query))
{
if($query_result = mysql_result($query_run, 0, $field1))
{
return $query_result;
}
}
}
That error that I'm getting has to do with the implementation of the getChallengeData method on page 2. The error says
Warning: mysql_result(): Unable to jump to row 0 on MySQL result index 10 in C:\xampp\htdocs\ChallengeNetworkWebsite\core.inc.php on line 42

$row[1] $row[2] $row[3]

_END;

If anyone can provide me with some incite as to how I could accomplish this I'd appreciate it greatly.
Please read more about sessions here
Then, to answer your question:
First you need to start the session, as simple as session_start(); on the top of your script.
Second you need to instantiate session variables with the DB values like this: $_SESSION['var'] = $value;.
Third, in the html file or whatever, where the form relies, just check for it:
if(isset($_SESSION['var'])) {
echo '<input type="text" value="'.$_SESSION['var'].'" />';
} else {
echo '<input type="text" value="" />';
}
and use the value if it is set.
L.E:
So... first thing's first... session_start(); without it, there is no point of having session.
Second, you create it like $_SESSION['some_name'] = $row[1] so that var will keep the value from $row[1]. I am presuming that it's the value you need. Do NOT do do it like $_SESSION['$row1'] because first of all this is incorrect, you will NOT have the value of row1 there. You need an unique name so that you can call it where you have the form.
The above code will become something like this:
<?php
session_start();
ini_set('display_errors',1); error_reporting(E_ALL);
$DATE = date('Y-m-d');
require_once 'IRCconfig.php';
$connection = new mysqli($db_hostname, $db_username, $db_password, $db_database);
if ($connection->connect_error) die($connection->connect_error);
$query = "SELECT * FROM CLIENT_CHECKIN1 WHERE DATE>='$DATE'";
$result = $connection->query($query);
if (!$result) die ("Database access failed: " . $connection->error);
$rows = $result->num_rows;
for ($j = 0 ; $j < $rows ; ++$j)
{
$result->data_seek($j);
$row = $result->fetch_array(MYSQLI_NUM);
$_SESSION['first_row'] = $row[1];
$_SESSION['second_row'] = $row[2];
$_SESSION['third_row'] = $row[3];
echo <<<_END
<pre>
$row[1] $row[2] $row[3]
</pre>
_END;
}
?>
and, where you have the form and the <input type = "text" value = "" /> so where you need the value, just do it like this:
<input type = "text" value = "<?php echo (isset($_SESSION['first_row']) ? $_SESSION['first_row'] : ''); ?>" />
<input type = "text" value = "<?php echo (isset($_SESSION['second_row']) ? $_SESSION['second_row'] : ''); ?>" />
<input type = "text" value = "<?php echo (isset($_SESSION['third_row']) ? $_SESSION['third_row'] : ''); ?>" />
Hope this helps! :D
