PHP getting days of a month for a database - php

I'm making a calender planner with php/css/javascript/html.
I am trying to set each day of the month a class which is "day". I tried using the following:
**PHP CODE**
error_reporting(E_ALL);
ini_set('display_errors', '1');
include "scripts/connect_to_mysql.php";
$jobNameValue ='';
$monthDays = '';
$monthname = '';
$days = '';
//getting values for job names
$sql_job_name = mysql_query("SELECT * FROM jobs");
$num_job_name = mysql_num_rows($sql_job_name);
if($num_job_name >0) {
while ($row = mysql_fetch_array($sql_job_name)) {
$job_name = $row["job_name"];
$job_short_name = $row["job_short_name"];
$jobNameValue .= '<option value="' . $job_short_name . '">' . $job_name . '</option>';
}
} else {
$jobNameValue .= '<option value="NULL">No job listed</option>';
}
//getting values for months days
$sql_month_days = mysql_query("SELECT * FROM months");
$num_month_days = mysql_num_rows($sql_month_days);
if($sql_month_days > 0) {
while($row = mysql_fetch_array($sql_month_days)) {
$month_id = $row["id"];
$name = $row["name"];
$num_days = $row["num_days"];if($num_days === "31") {
for($i=1; $i <=31; $i++) {
$days .= '<span class="day">' . $i . '</span>';
}
} else {
if($num_days === "30") {
for($i=1; $i <=30; $i++) {
$days .= '<span class="day">' . $i . '</span>';
}
} else {
if($num_days === "29") {
for($i=1; $i <=29; $i++) {
$days .= '<span class="day">' . $i . '</span>';
}
}
}
}
$monthDays .= '<div id="monthContainer">
<span class="monthName">'. $name .'</span>
<div class="monthDaysContainter">
'. $days.'
</div>
</div>';
}
}
**HTML CODE**
<div id="container">
<div ="newJob">
<form action="<?php $_SERVER['PHP_SELF'] ?>" id="newJobForm">
<label for="jobName">Job Name:</label>
<select id="jobName">
<?php echo $jobNameValue; ?>
</select>
<input type="date">
<input type="submit" id="submit">
</form>
</div>
<div id="calander">
<?php echo $monthDays; ?>
</div>
</div>
It does not work correctly, it kept duplicating every month and I am not sure how to correctly right the php to achieve what was intended.
I am only a beginner at php so I am not good at the moment
Could anyone help me with this?
If there any more information you need, please don't hesitate to ask.
Thank you in advance!

Try just doing this and seeing if that fixes it, you don't need all of those if statements
for($i=1; $i <= $num_days; $i++) {
$days .= '<span class="day">' . $i . '</span>';
}

do not use ===,use ==,maybe your $num_days is integer

Your problem is that you are creating the whole thing in the while loop, so the days that are appended from the last call are also appended to the next output.
$tmpArray = array();
if($sql_month_days > 0) {
while($row = mysql_fetch_array($sql_month_days)) {
array_push($tmpArray, $row);
}
}
foreach($tmpArray as $k){
$monthDays .= '<div id="monthContainer"><span class="monthName">'. $k['name'] .'</span><div class="monthDaysContainter">'. calNumDays($k['num_days']).'</div></div>';
}
Update
Should you wish to keep what you already have
if($num_days === "31") {
$days = '';
for($i=1; $i <=31; $i++) {
$days .= '<span class="day">' . $i . '</span>';
}
} else {
if($num_days === "30") {
$days = '';
for($i=1; $i <=30; $i++) {
$days .= '<span class="day">' . $i . '</span>';
}
} else {
if($num_days === "29") {
$days = '';
for($i=1; $i <=29; $i++) {
$days .= '<span class="day">' . $i . '</span>';
}
}
}
}
You only really to need to reinitialize the $days before each for after the if

for loop not working correctly with json encode Php

I am trying to fetch members ratings from the database using ajax. I passed a function to the JSON, even though it returned a value in the function but it doesn't execute the for loop condition.
Here is my code, the loop failed to execute. What am I doing wrong?
function mrate($irate) {
$class = "fa-star star-filled";
for ($i = 0; $i < 5; $i++) {
if ($irate <= $i) {
$class = "fa-star-o empty";
}
return '<i class="fa ' . $class . '"></i>';
}
}
$perPage = 2;
if (isset($_GET["page"]) && isset($_GET["page"])) {
$page = $_GET["page"];
$pid = $mysqli->real_string_escape($_GET["pid"]);
} else {
$page = 1;
$pid = $mysqli->real_string_escape($_SESSION['pid']);
};
$startFrom = ($page - 1) * $perPage;
$sqlQuery = "SELECT id, name,
review, rating, added_date
FROM review_rating
where product_id = '$pid'
ORDER BY id ASC LIMIT $startFrom, $perPage";
$result = mysqli_query($mysqli, $sqlQuery);
$paginationHtml = '';
while ($row = mysqli_fetch_assoc($result)) {
$img = '<img class="rounded-circle" width="50" src="' . $set['installUrl'] . 'assets/img/login.png" alt="' . $row["name"] . '"/>';
$irate = $row['rating'];
$paginationHtml .= '<div class="product-review pb-4 mb-4 border-bottom">';
$paginationHtml .= '<div class="d-flex mb-3">';
$paginationHtml .= '<div class="media media-ie-fix align-items-center mr-4 pr-2">' . $img;
$paginationHtml .= '<div class="media-body pl-3"><h6 class="font-size-sm mb-0">' . $row["name"] . '</h6>';
$paginationHtml .= '<span class="font-size-ms text-muted">' . $row['added_date'] . '</span></div></div>';
$paginationHtml .= '<div><div class="star-rating">' . mrate($irate) . '</div></div>';
$paginationHtml .= '</div>';
$paginationHtml .= '<p class="font-size-md mb-2">' . $row['review'] . '</p>';
$paginationHtml .= '</div>';
}
$jsonData = array(
"html" => $paginationHtml,
);
echo json_encode($jsonData);
Replace your function mrate($irate) with this and try. You needed to concatenate the stars code to display it more than once.
function mrate($irate){
$stars = '';
for($i=0; $i<5; $i++){
if($irate <= $i){
$class = "fa-star-o empty";
}else{
$class = "fa-star star-filled";
}
$stars .= '<i class="fa '.$class.'"></i>';
}
return $stars;
}
Assuming there's no fractional rating, you can do the following - Display all 5 stars but solid ones will represent the rating.
function mrate($irate){
$class = '';
for($i = 0; $i < 5; $i++){
if ($irate <= $i) {
$class .= '<i class="fa fa-star"></i>';
} else {
$class .= '<i class="fa fa-star-o"></i>';
}
}
return $class;
}

Having some diffculty parsing tree data in ul li format in php

i'm try to create trial balance i somehow achieve tree view in my array and now i want to print my code but don't know how to make tree because i don't know how many children i can get in future and i'm not very good at recursion below is my tree prepared array and i also attach my result that i can make via foreach loop but stuck in children node i can make children nodes via foreach but the problem is it's not a best approach to follow so please help me out to print my tree structure data as per my array. Any help would be appreciated.
Here my tree array look like : Tree Array
My result look like this this is only root nodes of an array and i using jstree to show hierarchy.

PHP - Search results not paginating

I'm trying to get search results to paginate if there are greater than 10 items found in the database. For some reason, even though the code recognises there are more than 10 items and creates links for subsequent pages, all search results are listed on the first page only. Anyone able to help please? Code is below:
for($i = 0; $i < $terms_count; $i++)
{
$search_terms_array[$i] = trim($search_terms_array[$i]);
${"query".$i} = $this->mysqli_link->query("SELECT prod_id, prod_tags FROM table WHERE prod_tags LIKE '%" . $search_terms_array[$i] . "%'");
if(${"query".$i}->num_rows < 1)
{
$zerocount++;
}
else
{
$rows = array();
while($row = ${"query".$i}->fetch_array())
{
$rows[] = $row;
}
foreach($rows as $row)
{
$search_id_results[] = $row['prod_id'];
}
}
}
if($zerocount == $terms_count)
{
echo $this->err_handle->fetch_error_text("search_terms_0_results");
return;
}
else
{
$search_results = array_values(array_unique($search_id_results));
$search_results_count = count($search_results);
$search_page_count = ceil($search_results_count / 10);
$search_page_first_result = ($search_page - 1) * 10;
echo '<p>Go to page: ';
for($i = 1; $i <= $search_page_count; $i++)
{
if($i == $search_page)
{
echo " <strong>" . $i . "</strong>";
}
else
{
echo ' ' . $i . '';
}
}
echo '</p><p> </p><p> </p>';
for($i = 0; $i < $search_results_count; $i++)
{
$query = $this->mysqli_link->query("SELECT * FROM table WHERE prod_id='" . $search_results[$i] . "' LIMIT " . $search_page_first_result . ", 10");
while($row = $query->fetch_array())
{
echo "<h4>" . $row['prod_name'] . "</h4><p><img src=\"includes/images/product_images/" . $row['prod_category'] . "/" . $row['prod_pic_filename'] . "\" alt=\"\" width=\"150\" height=\"200\" /></p><p>Price: £" . $row['prod_price'] . "</p><p>" . $row['prod_code'] . "</p><input type=\"number\" name=\"prod_qty\" maxlength=\"2\" /><input type=\"submit\" name=\"add_to_basket\" value=\"Add To Basket\" /></form></p><p> </p><p> </p>";
}
}
echo '<p>Go to page: ';
for($i = 1; $i <= $search_page_count; $i++)
{
if($i == $search_page)
{
echo " <strong>" . $i . "</strong>";
}
else
{
echo ' ' . $i . '';
}
}
echo '</p><p> </p><p> </p>';
}
Ok so I found a solution to this problem and the full function is now as follows:
public function product_search($search_terms, $search_page, $search_flag_check)
{
if($search_flag_check == "invalid")
{
echo $this->err_handle->fetch_error_text("invalid_ns_term");
return;
}
if($search_terms == "")
{
echo $this->err_handle->fetch_error_text("no_search_string");
return;
}
$search_terms = htmlspecialchars($search_terms);
$search_terms = $this->mysqli_link->real_escape_string(filter_var($search_terms, FILTER_SANITIZE_FULL_SPECIAL_CHARS, FILTER_FLAG_NO_ENCODE_QUOTES));
$search_terms_array = explode(" ", $search_terms);
$terms_count = count($search_terms_array);
$zerocount = 0;
$search_id_results = array();
for($i = 0; $i < $terms_count; $i++)
{
$search_terms_array[$i] = trim($search_terms_array[$i]);
${"query".$i} = $this->mysqli_link->query("SELECT prod_id, prod_tags FROM table WHERE prod_tags LIKE '%" . $search_terms_array[$i] . "%'");
if(${"query".$i}->num_rows < 1)
{
$zerocount++;
}
else
{
$rows = array();
while($row = ${"query".$i}->fetch_array())
{
$rows[] = $row;
}
foreach($rows as $row)
{
$search_id_results[] = $row['prod_id'];
}
}
}
if($zerocount == $terms_count)
{
echo $this->err_handle->fetch_error_text("search_terms_0_results");
return;
}
else
{
$search_results = array_values(array_unique($search_id_results));
$search_results_count = count($search_results);
$search_page_count = ceil($search_results_count / 10);
$search_page_first_result = ($search_page - 1) * 10;
$search_page_results_limit = 10;
if($search_page_first_result < 1)
{
$search_page_first_result = 1;
}
echo '<p>Go to page: ';
for($i = 1; $i <= $search_page_count; $i++)
{
if($i == $search_page)
{
echo " <strong>" . $i . "</strong>";
}
else
{
echo ' ' . $i . '';
}
}
echo '</p><p> </p><p> </p>';
$search_page_upper_limit = $search_page_first_result + 9;
if(array_key_exists($search_page_upper_limit, $search_results))
{
$search_results_limit = $search_page_first_result + $search_page_results_limit;
}
else
{
end($search_results);
$search_results_limit = key($search_results);
reset($search_results);
}
for($i = $search_page_first_result; $i <= $search_results_limit; $i++)
{
$query2 = $this->mysqli_link->query("SELECT * FROM table WHERE prod_id='" . $search_results[$i] . "'");
$row = $query2->fetch_array();
echo "<h4>" . $row['prod_name'] . "</h4><p><img src=\"includes/images/product_images/" . $row['prod_category'] . "/" . $row['prod_pic_filename'] . "\" alt=\"\" width=\"150\" height=\"200\" /></p><p>Price: £" . $row['prod_price'] . "</p><p>" . $row['prod_code'] . "</p><input type=\"number\" name=\"prod_qty\" maxlength=\"2\" /><input type=\"submit\" name=\"add_to_basket\" value=\"Add To Basket\" /></form></p><p> </p><p> </p>";
}
echo '<p>Go to page: ';
for($i = 1; $i <= $search_page_count; $i++)
{
if($i == $search_page)
{
echo " <strong>" . $i . "</strong>";
}
else
{
echo ' ' . $i . '';
}
}
echo '</p><p> </p><p> </p>';
}
}
It took a bit of thinking and I was about to give up, but then I thought about using the array keys to calculate the limits for each search page and after a bit of googling on relevant PHP array functions it all fell into place quite well.
I understand the code may not be very tidy right now and there may be ways to optimize/improve it, however for the time being it does the job.

PHP get results from mysql in a for() loop

$thumb_p .= "\n</div>\n</li>\n";
it should wrap <div class=\"row-wrapper\"> between <li></li> after every three occurrences.
Problem is that i get one extra line at the bottom every time:
<li>
<div class="row-wrapper">
</div>
</li>
Consider this line
$thumb_p .= "</li>\n<li>";
Does it not cause you trouble? I think it should be
$thumb_p .= "<li>\n</li>";
