Create multi-row tables in PHP using MySQL - php

I'm trying to create something like the following:
But my current code has given me:
The part in white is what I get with the code below, and the part in black is what I get when I add in two more <td> rows. The problem is I can't get 3 pieces of data per row to be created - only vertically or horizontally.
$result = mysqli_query($con,"SELECT * FROM show_listing");
while($row = mysqli_fetch_array($result))
{
echo "<table>
<tr>
<td>".$row['name']."'</td>
</tr>
</table>";
}
mysqli_close($con);
It may be simpler than I think but does anyone know how I could do this?

$c = 0;
echo "<table>";
while($row = mysqli_fetch_array($result))
{
if ($c%3 == 0) {
if ($c) echo "</tr>";
echo "<tr>";
}
echo "<td>".$row['name']."</td>";
$c++;
}
if ($c) echo "</tr>";
echo "</table>";

You have the correct idea. You do not want the declaration in the while loop as the result is that you will get multiple tables.
So I moved the table declarations outside of the while loop. I also made the declarations conditional based on the current column. You can now set the variable $columns to however many columns you want.
$result = mysqli_query($con,"SELECT * FROM show_listing");
echo "<table>"
$columns=3;
$current_column=1;
while($row = mysqli_fetch_array($result))
{
if($current_column==1) {
echo "<tr>";
}
echo "<td>".$row['name']."'</td>";
if($current_column==$columns) {
echo "</tr>";
$current_column=1;
} else
$current_column++;
}
echo "</table>
mysqli_close($con);

Using OOP with PDO

I am using a class that fetches information from a database and shows that information in a table, along with an edit and delete button. When I click the edit or delete button, I want to add $_GET['id'] to the link, but I am confused on how to accomplish this.
public function select($tName,$from,$where=1){
$key=[];
$con=$this->con;
$sql="SELECT $tName FROM $from WHERE $where";
$data = $con->query($sql);
$fullRec=[];
foreach($data as $k=>$rows){
$fullRec[]=$rows;
}
foreach($rows as $k=>$v){
$key[] = $k;
}
//create table
echo "<table border='1'>";
//create one row with col name selected!!
echo "<tr>";
for($z=0;$z<count($key);$z+=2){
echo "<td>".$key[$z]."</td>";
}
echo "<td>actions</td>";
echo "</tr>";
//create one row for each record comes!!
for($i=0;$i<count($fullRec);$i++){
echo "<tr>";
//create one table data for each record comes!!
for($j=0;$j<count($fullRec[$i])/2;$j++){
echo "<td>".$fullRec[$i][$j]."</td>";
}
echo "<td>EditDelete</td>";
echo "</tr>";
}
echo "</table>";
}
use like this to pass the id of the record in get parameter
echo "<a href='your_route?del=".$rows['id']."'>DELETE</a>";

Create dynamic table in php with mysql data

I would to like to create a dynamic table that the rows and columns of the table depends on the data in mysql data. Please see below my codes.
<?php
require "connect/db.php";
$query = mysqli_query($mysqli, "SELECT COUNT(level) level, shelf_no, bin_id FROM location_bin WHERE rack_id =1 GROUP BY shelf_no");
while($res=mysqli_fetch_array($query)){
$col = $res['level']; //col
$row = $res['shelf_no']; //rows
echo "<table border='1'>";
$i = 0;
while ($i < $col){
if ($i==$col){
echo "<tr>";
}
echo "<td>".$res['bin_id']."</td>";
$i++;
}
echo "</tr>";
echo "</table>";
}
?>
What I want is to display A-1-01 up to A-1-06 in the first row then A-2-01 to A-2-03 on the second row. Note that the data is dynamic.
Can you try this code . It works. change db.php path as your system path.
require "db.php";
$query = mysqli_query($conn, 'SELECT level, shelf_no, bin_id FROM location_bin ORDER BY shelf_no asc, level asc ');
echo "<table border='1'>";
echo "<tr>";
$i=0;
while($res = mysqli_fetch_assoc($query)) {
$row=$res['shelf_no'];
if ($i < $row){
$i=$row;
echo "</tr><tr>";
}
echo "<td>".$res['bin_id']."</td>";
}
echo "</table>";
?>

Fetch complex table data from database

I have a table in database and I want to fetch the data from it. I know how to fetch data from database using php. But the problem is that
this table is different in structure. For example
and so on...
As you can see this table is like a pivot table. That is the real problem for me. All the entries of a single person should be in single row. But it is in different rows and single column (all entries of single person is in value column).
I have tried to fetch table with regular way like this
<?php
/*
Template Name: Registration
*/
get_header();
$results = $wpdb->get_results( "SELECT * FROM wp_cf_form_entry_values", ARRAY_A );
$count = $results->num_rows;
if(!empty($results)) {
echo "<table width='100%' border='1' cellspacing='1'>";
echo "<tbody>";
foreach($results as $row){
echo "<tr>";
echo "<td><center>" . $row['value'] . "</center></td>";
echo "</tr>";
}
echo "</tbody>";
echo "</table>";
} else {
echo "<table width='100%' border='1' cellspacing='1'><tr><td>No Records Found</td></tr></table>";
}
get_footer();?>
But with the above code it's showing all the results in a single column and that's what I expect from above code.
So I don't know the correct code to represent this table as single row entries of single person. I searched a lot but didn't get much.
I'm pretty sure you looking for something like this:
horizontal representation: (by Person)
<?php
/*
Template Name: Registration
*/
get_header();
global $wpdb;
//Create a mulit dimensional array for each person.
$persons = array();
$fields = $wpdb->get_results( 'SELECT * FROM wp_cf_form_entry_values');
foreach($fields as $field){
$persons[$field->entry_id][$field->slug] = $field->value;
}
//the table
echo '<table width="100%" border="1" cellspacing="1">';
$i=0;
foreach($persons as $id=>$values){
//the table header (only in the first loop)
if($i==0){
echo '<tr>';
foreach($values as $key=>$val){
echo '<th>'.$key.'</th>';
}
echo '</tr>';
}
// one line per person
echo '<tr id="'.$id.'">';
foreach($values as $key=>$val){
echo '<td>'.$val.'</td>';
}
echo '</tr>';
$i++;
}
if($i==0){
echo "<table width='100%' border='1' cellspacing='1'><tr><td>No Records Found</td></tr></table>";
}
echo '</table>';
get_footer();?>
vertical representation (by field slug)
<?php
/*
Template Name: Registration
*/
get_header();
global $wpdb;
//Create a mulit dimensional array for each slug.
$field_slugs = array();
$fields = $wpdb->get_results( 'SELECT * FROM wp_cf_form_entry_values');
foreach($fields as $field){
$field_slugs[$field->slug][$field->entry_id] = $field->value;
}
//the table
echo '<table width="100%" border="1" cellspacing="1">';
$i=0;
foreach($field_slugs as $slug=>$values){
//the table header (only in the first loop)
if($i==0){
echo '<tr>';
foreach($values as $person_id=>$val){
echo '<th></th>';
echo '<th>Person '.$person_id.'</th>';
}
echo '</tr>';
}
// one line per person
echo '<tr id="'.$slug.'">';
echo '<td><b>'.$slug.'</b></td>';
foreach($values as $person_id=>$val){
echo '<td>'.$val.'</td>';
}
echo '</tr>';
$i++;
}
if($i==0){
echo "<table width='100%' border='1' cellspacing='1'><tr><td>No Records Found</td></tr></table>";
}
echo '</table>';
get_footer();?>
You use foreign key entries_id so you can retrieve from that table ie
$results=$wpdb->get_results("select * from entries_table");
foreach($results as $result){
$entries_id=$result->id;
$entry_detail=$wpdb->get_results(SELECT * from form_field_table where entries_id='$entries_id' ");
foreach($entry_detail as $ent_detail){?>
<td><?php echo $ent_detial->slug;?></td><td><?php echo $ent_detial->value;?></td>
<?php }
}

$row how to get all data into vars

I am building an page the script is done it lists Name and Points in a table. But when i gonna do the design it will be to hard to do it with "echo". So i am woundering if i can get this into vars insted that i can just use in a html file.
Table look like this
Name | Points | Date
What i want is to make a var for the 10 first name rows and a var for the 10 first point rows.
Like
$top1n = $row[0]'name'
$top1p = $row[0]'points'
$top2n = $row[1]'name'
$top2p = $row[1]'points'
$top3n = $row[2]'name'
$top3p = $row[2]'points'
$top4n = $row[3]'name'
$top4p = $row[3]'points'
And so on...
etc.
See my script below
echo "<table border='1'>";
echo "<tr> <th>Name</th> <th>Tokens</th> </tr>";
// keeps getting the next row until there are no more to get
while($row = mysql_fetch_array( $resultbtm )) {
// Print out the contents of each row into a table
echo "<tr><td>";
echo $row['Name'];
echo "</td><td>";
echo $row['points'];
echo "</td></tr>";
}
echo "</table>";
Is this what you want?
$names = array();
$points = array();
while($row = mysql_fetch_array($resultbtm)) {
$names[] = $row['Name'];
$points[] = $row['tokens'];
}
echo '<pre>';
print_r($names);
print_r($points);
echo '</pre>';
Not 100% sure if this is what you were looking for, but the $names and $points variables will be arrays containing the Names and Tokens (respectively) from your mysql result set.
Side note: mysql_* functions are deprecated as of PHP 5.5.0 due to security issues. If you are able to it is strongly recommended you switch to mysqli_* or PDO.
You can do it like this: (no need to create so many variables)
$str = "<table border='1'>";
$str .= "<tr> <th>Name</th> <th>Tokens</th> </tr>";
// keeps getting the next row until there are no more to get
while($row = mysql_fetch_array( $resultbtm )) {
// Print out the contents of each row into a table
$str .= "<tr>";
$str .= "<td>".$row['Name']."</td><td>".$row['points']."</td>";
$str .= "</tr>";
}
$str .= "</table>";
echo $str;
You could use extract
echo "<table border='1'>";
echo "<tr> <th>Name</th> <th>Tokens</th> </tr>";
// keeps getting the next row until there are no more to get
$c = 1;
while($row = mysql_fetch_array( $resultbtm )) {
${'top'.$c.'n'} = $name;
${'top'.$c.'p'} = $points;
$c++;
// Print out the contents of each row into a table
echo "<tr><td>$Name</td><td>$tokens</td></tr>";
}
echo "</table>";

How to echo out table rows from the db (php)

i want to echo out everything from a particular query. If echo $res I only get one of the strings. If I change the 2nd mysql_result argument I can get the 2nd, 2rd etc but what I want is all of them, echoed out one after the other. How can I turn a mysql result into something I can use?
I tried:
$query="SELECT * FROM MY_TABLE";
$results = mysql_query($query);
$res = mysql_result($results, 0);
while ($res->fetchInto($row)) {
echo "<form id=\"$row[0]\" name=\"$row[0]\" method=post action=\"\"><td style=\"border-bottom:1px solid black\">$row[0]</td><td style=\"border-bottom:1px solid black\"><input type=hidden name=\"remove\" value=\"$row[0]\"><input type=submit value=Remove></td><tr></form>\n";
}
$sql = "SELECT * FROM MY_TABLE";
$result = mysqli_query($conn, $sql); // First parameter is just return of "mysqli_connect()" function
echo "<br>";
echo "<table border='1'>";
while ($row = mysqli_fetch_assoc($result)) { // Important line !!! Check summary get row on array ..
echo "<tr>";
foreach ($row as $field => $value) { // I you want you can right this line like this: foreach($row as $value) {
echo "<td>" . $value . "</td>"; // I just did not use "htmlspecialchars()" function.
}
echo "</tr>";
}
echo "</table>";
Expanding on the accepted answer:
function mysql_query_or_die($query) {
$result = mysql_query($query);
if ($result)
return $result;
else {
$err = mysql_error();
die("<br>{$query}<br>*** {$err} ***<br>");
}
}
...
$query = "SELECT * FROM my_table";
$result = mysql_query_or_die($query);
echo("<table>");
$first_row = true;
while ($row = mysql_fetch_assoc($result)) {
if ($first_row) {
$first_row = false;
// Output header row from keys.
echo '<tr>';
foreach($row as $key => $field) {
echo '<th>' . htmlspecialchars($key) . '</th>';
}
echo '</tr>';
}
echo '<tr>';
foreach($row as $key => $field) {
echo '<td>' . htmlspecialchars($field) . '</td>';
}
echo '</tr>';
}
echo("</table>");
Benefits:
Using mysql_fetch_assoc (instead of mysql_fetch_array with no 2nd parameter to specify type), we avoid getting each field twice, once for a numeric index (0, 1, 2, ..), and a second time for the associative key.
Shows field names as a header row of table.
Shows how to get both column name ($key) and value ($field) for each field, as iterate over the fields of a row.
Wrapped in <table> so displays properly.
(OPTIONAL) dies with display of query string and mysql_error, if query fails.
Example Output:
Id Name
777 Aardvark
50 Lion
9999 Zebra
$result= mysql_query("SELECT * FROM MY_TABLE");
while($row = mysql_fetch_array($result)){
echo $row['whatEverColumnName'];
}
$sql = "SELECT * FROM YOUR_TABLE_NAME";
$result = mysqli_query($conn, $sql); // First parameter is just return of "mysqli_connect()" function
echo "<br>";
echo "<table border='1'>";
while ($row = mysqli_fetch_assoc($result)) { // Important line !!!
echo "<tr>";
foreach ($row as $field => $value) { // If you want you can right this line like this: foreach($row as $value) {
echo "<td>" . $value . "</td>";
}
echo "</tr>";
}
echo "</table>";
In PHP 7.x You should use mysqli functions and most important one in while loop condition use "mysqli_fetch_assoc()" function not "mysqli_fetch_array()" one. If you would use "mysqli_fetch_array()", you will see your results are duplicated. Just try these two and see the difference.
Nested loop to display all rows & columns of resulting table:
$rows = mysql_num_rows($result);
$cols = mysql_num_fields($result);
for( $i = 0; $i<$rows; $i++ ) {
for( $j = 0; $j<$cols; $j++ ) {
echo mysql_result($result, $i, $j)."<br>";
}
}
Can be made more complex with data decryption/decoding, error checking & html formatting before display.
Tested in MS Edge & G Chrome, PHP 5.6
All of the snippets on this page can be dramatically reduced in size.
The mysqli result set object can be immediately fed to a foreach() (because it is "iterable") which eliminates the need to maked iterated _fetch() calls.
Imploding each row will allow your code to correctly print all columnar data in the result set without modifying the code.
$sql = "SELECT * FROM MY_TABLE";
echo '<table>';
foreach (mysqli_query($conn, $sql) as $row) {
echo '<tr><td>' . implode('</td><td>', $row) . '</td></tr>';
}
echo '</table>';
If you want to encode html entities, you can map each row:
implode('</td><td>' . array_map('htmlspecialchars', $row))
If you don't want to use implode, you can simply access all row data using associative array syntax. ($row['id'])
