i am facing problem, my php show all pages in row and its increasing day by day as i upload data on my sql. I just want 25 page result on page and other for click to next.
<?php
if(isset($page))
{
$result = mysql_query("select Count(*) As Total from store_urls");
$rows = mysql_num_rows($result);
if($rows)
{
$rs = mysql_fetch_assoc($result);
$total = $rs["Total"];
}
$totalPages = ceil($total / $perpage);
if($page <=1 ){
echo "<span id='page_links' style='font-weight: bold;float:left;'>Prev</span>";
}
else
{
$j = $page - 1;
echo "<span style='float:left;'><a style='padding: 8px;' id='page_a_link' href='url_lists.php?page=$j'>< Prev</a></span>";
}
for($i=1; $i <= $totalPages; $i++)
{
if($i<>$page)
{
echo "<span><a style='float:left;padding: 8px;' id='page_a_link' href='url_lists.php?page=$i'>$i</a></span>";
}
else

I have a problem with making a query to MYSQL which will combine two tables.
Mainly I want to through such a query
<?php
require_once 'dbconnect.php';
$wynik = mysql_query("SELECT * FROM users")
or die('Błąd zapytania');
/*
wyświetlamy wyniki, sprawdzamy,
czy zapytanie zwróciło wartość większą od 0
*/
if(mysql_num_rows($wynik) > 0) {
/* jeżeli wynik jest pozytywny, to wyświetlamy dane */
echo "<table cellpadding=\"2\" border=1>";
while($r = mysql_fetch_assoc($wynik)) {
echo "<tr>";
echo "<td><a href='pokaz.php?id=".$r['userId']."'>".$r['userName']."</a></td>";
echo "</tr>";
}
echo "</table>";
}
?>
and after clicking on the link, the pictures that this user added showed me
the file pokaz.php looks like this
my tables
Please, let someone ask me this question, I will be grateful
use mysqli:
<?php
$con = mysqli_connect("localhost","my_user","my_password","my_db");
$wynik = mysqli_query($con, "select `user`.userId, `user`.userName, `pictures`.image_name from `user` inner join `user_uploads` on `user_uploads`.user_id_fk = `user`.id");
/*
wyświetlamy wyniki, sprawdzamy,
czy zapytanie zwróciło wartość większą od 0
*/
if($wynik) {
if (mysqli_num_rows($wynik) > 0) {
;
/* jeżeli wynik jest pozytywny, to wyświetlamy dane */
echo "<table cellpadding=\"2\" border=1>";
while ($r = mysqli_fetch_assoc($wynik)) {
$imgName = $r['image_name'];
echo "<tr>";
echo "<td><a href='pokaz.php?id=" . $r['userId'] . "'>" . $r['userName'] . "</a></td>";
echo "<img src='/uploads/$imgName' />";
echo "</tr>";
}
echo "</table>";
}
}
?>
UPDATE:
if you want to show images in pokaz.php for each user:
<?php
$con = mysqli_connect("localhost","my_user","my_password","my_db");
$wynik = mysqli_query($con, "select `user`.userId, `user`.userName, `pictures`.image_name from `user` inner join `user_uploads` on `user_uploads`.user_id_fk = `user`.id");
/*
wyświetlamy wyniki, sprawdzamy,
czy zapytanie zwróciło wartość większą od 0
*/
if($wynik) {
if (mysqli_num_rows($wynik) > 0) {
;
/* jeżeli wynik jest pozytywny, to wyświetlamy dane */
echo "<table cellpadding=\"2\" border=1>";
while ($r = mysqli_fetch_assoc($wynik)) {
$imgName = $r['image_name'];
echo "<tr>";
echo "<td><a href='pokaz.php?id=" . $r['userId'] . "'>" . $r['userName'] . "</a></td>";
echo "<img src='/uploads/$imgName' />";
echo "</tr>";
}
echo "</table>";
}
}
?>
pokaz.php
<?php
if(isset($_GET['userId'])){
$userId = $_GET['userId'];
$con = mysqli_connect("localhost","my_user","my_password","my_db");
$query = "select image_name from user_uploads";
$result = mysqli_query($con, $query);
if($result){
while($row = mysqli_fetch_assoc($result)){
$imgName = $row['image_name'];
echo "<img src='/uploads/$imgName' /></br>";
}
}
}
I have a form which displays mysql data in the form of an HTML table, using pagination of 5 records per page. I'm trying to export my table to excel, but it's only exporting data of the rows that are currently show, meaning if there are 20 rows, it only shows the first 5 as those get displayed. How can I make it export the one's that are not being displayed but still part of the search? I saw a few other people with a similar question but none have answers( How to export all HTML table rows to Excel file from a paginated table?). Hopefully I can get one!
<?php
if(isset($_GET['submit']) || isset($_GET['page'])){
// Setting up the Pagination below

$page_query = "SELECT * FROM tbl_call_log_detail ";
$page_query .= "WHERE

OR ( Time <= '$endDate' AND Time >= '$startDate'
AND (dealer_id = '$call_id' OR'$call_id'='' ))
OR ('$endDate'='1970-01-01' AND '$startDate' ='1970-01-01' AND '$call_id'='') ";
$page_result = mysqli_query($conn, $page_query);
$total_records = mysqli_num_rows($page_result);

UPDATE: Found the answer I was looking for I simply ran a new sql query without the LIMIT clause and stored it in a hidden table. I then use the hidden table to export data
// SQL and hidden table for exporting to excel
$page_query2 = "SELECT * FROM tbl_call_log_detail ";
$page_query2 .= "WHERE
(dealer_id = '$call_id' AND '$endDate'='1970-01-01' AND '$startDate' ='1970-01-01')
OR ( Time <= '$endDate' AND Time >= '$startDate'
AND (dealer_id = '$call_id' OR'$call_id'='' ))
OR ('$endDate'='1970-01-01' AND '$startDate' ='1970-01-01' AND '$call_id'='') ORDER BY TIME DESC ";
$page_result2 = mysqli_query($conn, $page_query2);
$row2 = mysqli_num_rows($page_result2);
$all_property2 = array();
echo "<table class = 'data-table2' border = '1' cellpadding = '9' bgcolor = '#CCCCCC' id = 'data-table2' hidden>
<tr class = 'data-heading2'>";
while($property = mysqli_fetch_field($page_result2)){
echo '<td><b> '. $property ->name. ' </b></td>';
array_push($all_property2, $property ->name);
}
echo '</tr>';
while ($row2 = mysqli_fetch_array($page_result2)){
echo '<tr>';
foreach($all_property2 as $item){
echo '<td> '. $row2[$item] . ' </td>';
}
echo '</tr>';
echo '</center>';
}
echo '</table>';

<input type = "submit" onclick = "window.open('data:application/vnd.ms-excel, '+encodeURIComponent(document.getElementById('data-table2').outerHTML));" value = "Export into excel" />

You can use JQuery table2excel plugin following is the link
http://www.jqueryscript.net/table/Export-Html-Table-To-Excel-Spreadsheet-using-jQuery-table2excel.html
Try following code pen to only JavaScript

I'm constructing a survey and I have a textbox that generates dynamic dropdowns based on user input which displays the same data.
This is the script
<script>
function load_questions(){
var xmlhttp=new XMLHttpRequest();
xmlhttp.open("GET","ajax.php??main=1&subcategory="+document.getElementById("subcategorydd").value +"&cnt="+document.getElementById("q_num").value,false);
xmlhttp.send(null);
document.getElementById("question").innerHTML=xmlhttp.responseText;
}
function checkValues() {
_values = [];
$('.form-control-static').each(function() {
_values.push($(this).val());
//console.log($(this).val());
});
sameValue = false;
for ($i = 0; $i < (_values).length; $i++) {
for ($w = 0; $w < (_values).length; $w++) {
if (_values[$i] === _values[$w] && $i != $w) {
sameValue = true;
}
}
}
if (sameValue) {
alert('has the same value .');
return false;
}
alert('there is no the same value');
//do something .
}
</script>
This is the insert code when I'm creating the survey
<?php
$con = mysqli_connect("localhost","root","","imetrics");
if(isset($_POST['submit'])){
$title = $_POST['surveytitle'];
$catdd = $_POST['catdd'];
$subcatdd = $_POST['subcatdd'];
$gender = $_POST['gender'];
$age = $_POST['age'];
$occupation = $_POST['occupation'];
$occupationtwo = $_POST['occupdd'];
$relstatus = $_POST['relationshipstatus'];
$q_num = $_POST['q_num'];
$insert = mysqli_query($con, "INSERT INTO `surveyform` (`surveytitle`,`surveycategory`,`surveysubcategory`,`gender`,`age`,`occupation`,`occupation_status`,`status`) VALUES ('$title','$catdd','$subcatdd','$gender','$age','$occupation','$occupationtwo','$relstatus')");
if(!$insert){
echo mysqli_errno();
}
else{
$getMaxID = mysqli_query($con, "SELECT MAX(survey_id) as maxid FROM surveyform");
$row_2 = mysqli_fetch_array($getMaxID);
$survey_id = $row_2[0];
for( $a = 1; $a <= $q_num; $a++)
{
mysqli_query($con, "INSERT INTO surveyform_questions ( survey_id, question_id) VALUES ('$survey_id', ". $_POST['question_dropdowns'.$a] .")");
//echo "INSERT INTO surveyform_questions ( survey_id, question_id) VALUES ('$survey_id', ". $_POST['question_dropdowns'.$a] .")";
}
echo '<script language="javascript">';
echo 'alert("Survey Created!")';
echo '</script>';
}
}
?>
And this is my dropdown code
if($question !="" && $cnt!="" && $addQues!="yes" && $main != 1){
$i = 0;
for ($i = 1; $i <= $cnt; $i++)
{
$query=mysqli_query($con, "SELECT * FROM question WHERE question_subcat = $question ");
echo "<b>Question #". $i."</b>";
echo "<select id='question_dropdown".$i."' class='form-control-static' name='question_dropdowns".$i."'>";
echo "<option selected>"; echo "Select"; echo "</option>";
while($row=mysqli_fetch_array($query))
{
echo "<option value='$row[question_id]'>";
echo $row["questiontitle"];
echo "</option>";
}
echo "</select>";
echo "<br />";
}
echo "<div id='insertQuesHere".$i."'></div>";
echo "<a href='#add_question' onclick='return addQues();'>Add Question</a>";
}
here's my submit button
<input type="submit" name="" id="btnSaveSurvey" class="form-control-static" onclick="checkValues();" value="check" />
What's the validation code that will prevent me from inserting if the data chosen from the dropdown is the same? For example I generated 2 dropdowns and I chose the same datas from the dropdown, what's the validation code for it?
Please call checkValues method your submit button click
<input type="submit" name="" id="btnSaveSurvey" class="form-control-static" onclick="checkValues();" value="check" />
checkValues method below :
function checkValues() {
_values = [];
$('.form-control-static').each(function() {
_values.push($(this).val());
//console.log($(this).val());
});
sameValue = false;
for ($i = 0; $i < (_values).length; $i++) {
for ($w = 0; $w < (_values).length; $w++) {
if (_values[$i] === _values[$w] && $i != $w) {
sameValue = true;
}
}
}
if (sameValue) {
alert('has the same value .');
return false;
}
alert('there is no the same value');
//do something .
}
Also , you can see an example Example
I made a line chart with chart.js. For the values is some PHP script added. The axis only displayed the timestamp numbers. When I use a PHP function for timestamp conversion:
<?php echo date('H:i', $time); ?>
It totally crashes.
This is my code for the PHP time echo. How can I display HH:ii on my X axis of the chart?
<?php
$total = (count($data)) - 1;
if ($total > 100) {
$start = $total - 100;
$end = $total;
}
else {
$start = 0;
$end = $total;
}
for ($x = $start; $x < $end; $x++) {
if ($x % 5 == 0) {
//echo $x; //5th element
$row = $data[$x];
$time = intval($row->{'time'});
echo $time;
} else{
echo ' '; //prints empty for other than 5th element
}
echo ', '; //prints ',' for every element
Fixed it with:
echo '\'' . date('H:i', $time) . '\'';
I am very new to jQuery and JavaScript. I have a small question. Let's say i have a HTML table like the following
<?php
include 'dbconnect.php';
$sql = "SELECT * FROM Comments";
$result = mysqli_query($conn,$sql);
if (!$result) {
echo '<div>no comments were set up</div>';
}
$fields_num = mysqli_num_fields($result);
echo "<h1>Table: {$table}</h1>";
echo "<table id='myTable' border='1'><tr>";
// printing table headers
for($i=0; $i<$fields_num; $i++)
{
$field = mysqli_fetch_field($result);
echo "<td>{$field->name}</td>";
}
echo "</tr>\n";
// printing table rows
while($row = mysqli_fetch_row($result))
{
echo "<tr>";
// $row is array... foreach( .. ) puts every element
// of $row to $cell variable
foreach($row as $cell)
echo "<td>$cell</td>";
//delete button
echo "<td><input type='button' value='Delete' onclick='deleteRow(this)'></td>";
//checkbox button
echo "<td><input type='checkbox' value='Highlight' onclick='highlight(this)'></td>";
echo "</tr>\n";
}
mysqli_free_result($result);
?>
I want to check if the date in the 8th column is older than a day the row should be highlighted. How can I proceed.
i found a code but this is not working:
function checkdate(){
$('#myTable tr td').each(function () {
var dtTd = new Date($(this).html());
var dtNew = new Date();
// 15 minutes is 900000 milliseconds
// getTime() doc - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/getTime
if (dtTd.getTime() - dtNew.getTime() < 900000 && dtNew < dtTd) {
$(this).css("background-color", "red");
} else {
if (dtNew > dtTd) {
$(this).css("background-color", "yellow");
}
}
});
}
Try this:
$date = date('Y-m-d');
foreach($row as $cell)
{
if($cell['date'] < $date)
{
// for date less then today's date
}
else
{
// for others date
}
}
