I want to make an attendance list in which the date entered in the input form is put in the header of the right 3rd column. In the headers of the following columns, this date is incremented by 7 days.
I have three questions:
Why is the date not filled in the headers?
How can I insert the html table in the if statement?
How can I make the width of date columns 1 character big?
I created an input form forum.php and an action-script gen-table.php.
Inputform forum.php:
<!DOCTYPE html>
<html>
<style>
td, th {
border: 4px solid lightblue;
text-align: left;
padding: px;
}
</style>
<h2> ATTENDANCE LIST </h2>
</head>
<body>
<form action="gen-table.php" method="post">
<p>
<label for="startdate">Startdate:</label>
<input type="date" name="startdate" id="startdate" />
<input type="submit" value="Select and Activate" />
</p>
</body>
</html>
Action script gen-table.php:
<!DOCTYPE html>
<html>
<style>
td, th {
border: 4px solid lightblue;
text-align: left;
padding: px;
}
</style>
<h2> ATTENDANCE LIST </h2>
</head>
<?php
if (isset($_POST[startdate])) {
$day1 = date('d-m-Y',strtotime(startdate ."+0 Days"));
$day2 = date('d-m-Y',strtotime(startdate ."+7 Days"));
$day3 = date('d-m-Y',strtotime(startdate ."+14 Days"));
$day4 = date('d-m-Y',strtotime(startdate ."+21 Days"));
}
else
{
echo "Select startdate";
}
?>
<table>
<th>Lastname</th>
<th>Firstname</th>
<td><?php print $day1 ?> </td><td><?php echo $day2 ?></td><td><?php echo $day3 ?> </td><td><?php echo $day4 ?> </td>
</table>
</html>
Answer 1. Dates are not generating correctly. Inside strtotime() you should pass value from $_POST array.
Replace
date('d-m-Y',strtotime(startdate ."+0 Days"));
...
to
date('d-m-Y',strtotime($_POST['startdate'] . "+0 Days"));
...
Answer 2. You can dump html table with condition as follows-
<?php if(condition is true): ?>
html <table> goes here
<?php endif; ?>
Answer 3. Question is confusing, but according to my assumption you can use font size to make text bigger or use padding to give your text big space.

The above code work. The problem is when I select Java and PHP, I get PHP displayed in both tables. When I select 3 options, the last option get displayed in all tables. What I need is when I select e.g. PHP, JAVA, and UNIX/LINUX, the 3 options (PHP, JAVA, UNIX/LINUX) be displayed on the tables separately - PHP on the first table, Java on the second table and UNIX/LINUX on the third table.
When I select only 2 (e.g. Java and PHP), I want Java on the first table and PHP on the second.
Please help.
You have to write the row logic inside the loop.
<!DOCTYPE html>
<html>
<head>
<style>
table, th, td {
border: 1px solid black;
border-collapse: collapse;
}
th, td {

<h2>Cell that spans two columns</h2>
<p>To make a cell span more than one column, use the colspan attribute.</p>
<table style="width:50%">
<?php
if(isset($_POST['submit'])){
if(!empty($_POST['check_list'])) {
// Counting number of checked checkboxes.
$checked_count = count($_POST['check_list']);
foreach($_POST['check_list'] as $selected) {
echo "<p>".$selected ."</p>";
?>
<tr>

<td><?php echo $selected; ?></td>

<?php
}
}
else{
}
}
?>

</html>
Checkout the code below. You don't need to count the number of elements sepeartely as you are using foreach() loop already.
Also, just loop the table, not the complete HTML.
<?php
if(isset($_POST['submit'])){
if(!empty($_POST['check_list'])) {
//Counting number of checked checkboxes.
//$checked_count = count($_POST['check_list']);
?>
<!DOCTYPE html>
<html>

<style>
table, th, td {
border: 1px solid black;
border-collapse: collapse;

}
</style>

The date range picker won't work properly in my inventory report, but for the sales report it works properly.
E.g. From 2018-03-07 to 2018-03-08, the 2018-03-08 does not show in the report.
Picture of the report:
Here is my code
<head>
<script>
$(function() {
$( "#tabs" ).tabs();
$('a[rel*=facebox]').facebox();
$( ".datepicker" ).datepicker();
});
$(document).ready(function(){
// Write on keyup event of keyword input element
$("#searchme").keyup(function(){
// When value of the input is not blank
if( $(this).val() != "")
{
// Show only matching TR, hide rest of them
$("#searchTbl tbody>tr").hide();
$("#searchTbl td:contains-ci('" + $(this).val() + "')").parent("tr").show();
}
else
{
// When there is no input or clean again, show everything back
$("#searchTbl tbody>tr").show();
}
});
});
// jQuery expression for case-insensitive filter
$.extend($.expr[":"],
{
"contains-ci": function(elem, i, match, array)
{
return (elem.textContent || elem.innerText || $(elem).text() || "").toLowerCase().indexOf((match[3] || "").toLowerCase()) >= 0;

This is my inventory.php
In here the user can input the range date from , to .
I dont know if this will help you guys.
I just want to know why it does not work well.
The problem is when i input 2018-03-08 - 2018-03-08 , the march 7 shows up but the march 8 wont show up.
<form action="total_inventory.php" method="post">
From: <input type="text" class="datepicker" placeholder="E.G.(2018-01-14)" name="dayfrom" required pattern="[0-9]{4}+[0-9]+[0-9]"> To: <input type="text" class="datepicker" placeholder="E.G.(2018-02-11)" name="dayto" required pattern="[0-9]{4}+[0-9]+[0-9]">
<input type="submit" value="Show Report" name="salesbtn" ></form>
EDITED:
Here is my inventory table
INVENTORY DATA TABLE
UPDATED:
This is the output , still does not show the transaction from march 7
Sample Updated
There is time also in your table so you have to search with time. means your from should be d-m-Y 00:00:01 and your to should be d-m-Y 23:59:59
Updated : concat your date variables like this.
// Assume `$_POST['dayfrom'] = 03/15/2018;`
// Assume `$_POST['dayto'] = 03/31/2018;`
$from = date('Y-m-d', strtotime($_POST['dayfrom']))." 00:00:01";
$to = date('Y-m-d', strtotime($_POST['dayto']))." 23:59:59";
echo $from; // if date is `03/15/2018` output like `2018-03-15 00:00:01`
echo $to; // if date is `03/31/2018` output like `2018-03-31 23:59:59`
// NOTE: check your date format is like this or not, then run the SQL query.
Updated Query:
$iq=mysqli_query($conn,"select * from inventory left join product on product.productid=inventory.productid where ( inventory_date BETWEEN CAST('$from' AS DATE) AND CAST('$to' AS DATE) ) order by inventory_date desc ");
Following is the table i created for displaying the Restaurant Name, Location and Menu for table owners.
Now each of the row for the column Menu have Button as values.
My table is ready with perfect values.
NOW MY PROBLEM IS HOW TO DO:-
Upon clicking the button corresponding to the each Restaurant, a new File(openmenu.php) will open and will echo the Restaurant Name, Mobile Number of that Restaurant and the menu.
But so far, on clicking every Button ,I can only display above entries of the Last row of the table. Help Me Out. I am new to php.

Issue 1
In this snippet you are setting the session variables resphone and restaur to the values of the store you are currently iterating over. Over and over again. That's why you're only ever getting the last store's information - it's the last things you set those variables to.
while ($row = mysqli_fetch_array($query)){
$_SESSION['resphone'] = $row['resphone'];
$_SESSION['restaur'] = $row['restaur'];
Issue 2
You should probably change the form method to get and discard the unused hidden input like so:
<form method="post" action="openmenu.php?id=<?=$row['restaur']?>">
<input type="submit" value="View">
</form>
Or more likely just change it a plain old a link:
View
Issue 3
You're completely ignoring store id requested in openmenu.php. You are using $_SESSION where you should be using $_REQUEST or $_GET. I'm not going to give an example of how you should do that. Instead, please refer to this answer before moving any further.
first you getting data from database & then use view button for openmenu.php but why u use this way
<form method="post" action="openmenu.php?id=$row[restaur]"><input value="<?php echo $restaur;?>" type="hidden"><input type="submit" value="View"></form>
I have view file on my app there is code array I want to get first object of that array without going in loop.
<?php
$result = array_chunk($products->result_array(), 3);
foreach($result as $products){ ?>
<table style="width:100% style="page-break-after:always;" >
<tr>
<?php
foreach($products as $productArray){
$product = (object) $productArray;
echo '<td>';
?>
<div style="width: 100%; height: 210px; border: 1px solid #dddddd; margin: auto 5px 5px 0; padding: 5px;">
<div class="box-header">
<p class="box-title"><FONT SIZE=12><?php echo $product->product_name; ?></FONT></p>
</div>
<div style="height: 100px; text-align: center;">
<?php echo '<img src="'.'uploads/'. $product->photo.'" class="img-responsive" style="height:100px !important; width: 150px !important" />'; ?>
</div>

<table class="table table-responsive">
<tr>
<th><FONT SIZE=12>ID</FONT></th>
<td><FONT SIZE=14><?php echo $product->product_id; ?></FONT></td>
</tr>
$result is array of object I'm getting from a form. In below you can clearly see I'm chunking it to 3 more array and looping though individual objects and getting their details to html for example.
<tr>
<th><FONT SIZE=12>ID</FONT></th>
<td><FONT SIZE=14><?php echo $product->product_id; ?></FONT></td>
</tr>
I want to get the first object details let's say want get $product->product_name of first object of result array without going in loop how to achieve that.

ok man as i said u need to change your way of writing codes but about your specific question use this:
$result = array('a', 'b', 'c', 'd', 'e');
reset($array);
$first = current($array);
you can check this:
http://php.net/manual/en/function.reset.php
http://php.net/manual/en/function.current.php
But still about your way of coding. u should soon go to MVC or such ways of programming so u should separate your view and coding logics
like u may have a page like view_profile.php which is going to show user's information. in regular coding u have this:
view_profile.php:
<?php session_start();
// you check sessions to see if the user is logged in and has the right to view this page.
// like:
if ($_SESSIONS['is_user_logged_in']){
$username=$_SESSIONS['username'];
$name=$_SESSIONS['name'];
// ....
}else{
header('location: ./login.php');// if user is not authenticated u redirect to login page
exit();// prevents the rest of codes to be shown and executed
}
?>
<html>
<head>
<title>View <?php echo $name; ?>'s profile</title>
</head>
<body>
<div>Name: <span><?echo $name; ?></span></div>
......
</body>
</html>
But in a better way u can do it like this:
you have files like
'view_profile.htm' // holds the HTML
'view_profile.php // holds the PHP logic
'inc.php' // holds some useful functions that help you in writing PHP logic
view_profile.htm
<html>
<head>
<title>View <?php echo $name; ?>'s profile</title>
</head>
<body>
<div>Name: <span><?echo $name; ?></span></div>
......
</body>
</html>
inc.php
<?php
function ses_start(){
if(!session_id()){
session_start();
}
}
function ses_get($key){
ses_start();
if(!empty($_SESSION[$key])){
return $_SESSION[$key];
}
return NULL;
}
function ses_set($key,$val){
$_SESSION[$key]=$val;
}
function is_user_loggedin(){
ses_start();
if(!empty(ses_get('is_user_loggedin')){
return true;
}
return false;
}
function go($to){
header('location: '.$to);
exit();
}
//and lots of useful functions that help u connect and work with data base.
view_profile.php
<?php
include('inc.php');
if(is_user_loggedin(){
$username=ses_get('username');
$name=ses_get('name');
//...
}else{
go('login.php);
}
include('view_profile.html); // and u call the .htm file that holds the HTML the view file)
?>
this was a simple sample of separating codes logic(php codes) from views(html tags)
and also u may search about MVC Model-View-Controller and try working with simple MVC frameworks.
On a page I am working on, I have several distinct pieces of PHP, such as one in the head to handle dynamic Javascript and one in the main body for table creation. However, many of the operations, SQL queries, etc. are the same between the two area. For example, I keep having to reconnect to the same database over and over. Is there some way for me to streamline the code so that I do not need to have so much duplication and repeated calculation?
The page code, although it won't look right without the supplementary files. Also, it's very long.

You can re-use variables over and over on a single page. This would be a good idea for at least the database connection. Define $con just once at the top of the page and use it multiple times. Just because you close your php tag (?>) doesnt mean you lost your variables.
For code re-use, I would take a look at defining functions for common code fragments. Ideally, you would create classes to encapsulate logic. For example, it is typical to have a database connection object (or framework) which encapsulates connecting, querying, etc.
You may benefit from taking a look at the Zend Framework. It is a great tool for learning PHP developers to see industry standards on how to do many of things you are asking.

There are several ways to reuse code in php. The most basic and powerful one is the concept of functions.
