Query returns sum of elements group by operator (selected by checkbox).
How to sum up all that values? I tried using array_sum() but didn't worked or maybe i am not using this function correct.
Thank you
<?php
if(isset($_POST['delete']))
{
$ziua=$_POST["date"];
}
else
{
$ziua=date('Y-m-d');
}
if(isset($_POST['delete']))
{//check to see if the delete button has been pressed
if(isset($_POST['box']))
{ //check to see if any boxes have been checked
$num = 0;//used to count the number of rows that were deleted
$box = $_POST['box'];
foreach ($box as $key =>$val)
{ //loop through all the checkboxes
$num++;
$sqldel=" SELECT U.username , SUM(L.geometrie1) A from list L,users U where L.user_id='$val'
and L.date_posted like '%$ziua%' AND L.user_id=U.id group by U.username ";//delete any that match id
$resdel=mysql_query($sqldel);//send the query to mysql
while($row = mysql_fetch_array($resdel))
{
Print "<tr>";
Print '<td align="center">'. $row['0']. "</td>";
Print '<td align="center">'. $row['1']. "</td>";
Print "</tr>";
}
}
}
}
?>

Before you loop add
$total=0;
In your loop add
$total += $row[1];
Then echo it after the loop

I have following item list fetch from table, I need to add dynamic rowspan at the end of the row if item is from same supplier, but I have no idea how to work with this.
I tried:
foreach($items as $item){
/*get total num for rowspan*/
$group = $buyer->get_total_rowspan($obj->id, $obj->supplier);
echo '<tr>
<td>$item->id</td>
<td>$item->name</td>
<td>$item->supplier</td>';
if($group->countRow > 1){
<td rowspan="$group->countRow"><a>Manage</a></td>
}
if($group->countRow > 1){
echo '<td rowspan="'.$group->countRow.'"><a>manage</a></td>';
}else{
echo '<td><a>test</a></td>';
}
echo '</tr>';
}
but cell Manage will always appear at every row with mess format.
the idea results that I want:
You can try something like that:
$lastId = null;
foreach($items as $item){
/*get total num for rowspan*/
$group = $buyer->get_total_rowspan($obj->id, $obj->supplier);
echo '<tr>
<td>$item->id</td>
<td>$item->name</td>
<td>$item->supplier</td>';
if($lastId != $group->Id){
<td rowspan="$group->countRow"><a>Manage</a></td>
}
echo '</tr>'
$lastId = $group->Id;
}
Everytime there is a new group you can set the $i back to 0.
I use a MySql query to select data from my DB and then print it in the form of a HTML Table. It works perfectly, fine but sometimes the table consists of hundreds of rows and the webpage looks incredibly akward. Is there a way to split the table side by side into 2 or 3 halves.

Desired output
PHP
<?php
....
echo "<h3>Classes attended :</h3>";
echo "<table class='dates' border='1'>";
foreach ($results as $dates) {
echo "<tr><td width='50%'>";
echo $dates->db_date;
echo "</td>";
echo "<td width='50%'>";
echo $dates->day_name;
echo "</td>";
echo "</tr>";
}
echo "</table>";
?>
What would be the best way to achieve it?
Help would be appreciated.
You can use PHP to determine in your loop if the loop index is divisible by a certain number using something like this:
echo "<h3>Classes attended :</h3>";
echo "<table class='dates' border='1'>";
$rowCount = 1;
$numRows = count($results);
$maxRows = 12;
foreach ($results as $dates) {
echo "<tr><td width='50%'>";
echo $dates->db_date;
echo "</td>";
echo "<td width='50%'>";
echo $dates->day_name;
echo "</td>";
echo "</tr>";
if($rowCount % $maxRows == 0 && $rowCount != $numRows) {
echo "</table><table class='dates' border='1'>";
}
$rowCount ++;
}
echo "</table>";
That's the basics of doing this. Basically in your loop you're testing each index to see if it's divisible by $maxRows, and if so then you're going to close your table and open a new one. You'll have to add the styling to place the tables side by side.
If you wanted to expand upon this concept you can set $maxRows to be an evaluation of $numRows. For instance if you wanted to split the items as close as possible to half in order to show just two tables, you could do... $numRows = count($results); $maxRows = round($numRows / 2);
Inspired by Robert Wade's answer:
<?php
....
echo "<h3>Classes attended :</h3>";
$i=0;
$maxRows=10;
foreach ($results as $dates) {
$a=$i/$maxRows == 0 ? "<table class='dates' border='1'>":"";
$b=$i/$maxRows == 0 ? "</table>":"";
echo $a;
echo "<tr><td width='50%'>";
echo $dates->db_date;
echo "</td>";
echo "<td width='50%'>";
echo $dates->day_name;
echo "</td>";
echo "</tr>";
echo $b;
$i++;
}
?>
At last, add some css style to the tables.
You can also use array_chunk() for splitting your results. Or instead of displaing a lot of tables next to each other you can make pagination and get only some range in your query. For example:
SELECT * FROM `clients` LIMIT 5, 10
Selects 10 rows beggining from row 5. Now, when you change your page, just change limit values.
I tried to print the Mysql fetched rows into html table using php. However, when using the following code, the first fetched row is repeatedly printing. It looks like the $row hold the first fetched value. I found a similar problem here. But I would like to know about working with the for loop. Thanks
for ($j=0;$j<=$len2;$j++)
{
$sql = "SELECT * FROM database_search WHERE gene_id LIKE'%$key%'";
$qry = $dbo->prepare($sql);
$qry->execute();
$row = $qry->fetch(PDO::FETCH_ASSOC);
$val = array_values($row);
echo "<tr>";
for ($k=0;$k<=4;$k++)
{
$x=$val[$k];
echo "<td style=font-size:7.9px>$x</td>";
}
echo "</tr>";
}
<table>
<?php
while($row = $qry->fetch(PDO::FETCH_ASSOC)){
echo '<tr>';
foreach($row as $cell){ echo '<td>'.$cell.'</td>'; }
echo '</tr>';
}
?>
</table>
After fetching the query as $row variable, you need to use the following code instead
foreach($row as $tr) {
echo "<tr>";
echo "<td style=font-size:7.9px>".$tr['col1']."</td>";
echo "<td style=font-size:7.9px>".$tr['col2']."</td>";
echo "</tr>";
}
This is possible that $row only have one record fetching from database and than your for ($k=0;$k<=4;$k++) loop print that only one record 5 time
because you are using print under this loop, this loop will run 5 time.
Try the following code.
foreach($row as $val) {
echo "<tr>";
echo "<td style=font-size:7.9px>".$val['column Name']."</td>";
echo "</tr>";
}
Is there a php or html code to dynamically generate a table.
query :
"SELECT * FROM table1;
Can I display this grid of info without any specifics.
IF there are 4 rows and 4 columns I want the table to be that size; if 5x5 than that.
It seems like this should be possible, but all code I can find wants me to specify names or columns.
Yes. There are a couple different ways to do this, but for illustration I will assume that the result of your query is stored in a variable called $results, which is simply a multidimensional array that you can loop through using a double foreach to dynamically produce your table.
echo '<table>';
foreach ($results as $row) {
echo '<tr>';
foreach ($row as $col) {
echo '<td>' . $col . '</td>';
}
echo '</tr>';
}
echo '</table>';
OR if you don't have a $results array and are instead getting query results and building the table at the same time, something like this might be more appropriate for your needs:
echo '<table>';
while ($row = mysqli_fetch_array($query)) {
echo '<tr>';
foreach ($row as $col) {
echo '<td>' . $col . '</td>';
}
echo '</tr>';
}
echo '</table>';
echo'<table>';
while($row = mysql_fetch_array($result))
{
echo'<tr>';
echo '<td>'.$row[colname].'</td>';
echo '</tr>';
}
echo'</table>';
I have a database of images which I want to output as a gallery ...
I want to display each image in its own cell <td>image1</td> and limit the number of cells to 7 per row.
<tr>
<td>image1</td><td>image2</td><td>image3</td><td>image4</td><td>image5</td><td>image6</td><td>image7</td>
</tr>
Then a new row would be created and continue to output all the images.
<tr>
<td>image8</td>
and so on ..
I know how to do a query, but I am lost as to how to assemble the rows into the format I am looking for.
Can anyone please help me it would be greatly appreciated. Thanks.
First run your query, then get the mysql_fetch_assoc in a variable. Then echo your beginning tags for the table and tr. Then create a foreach loop of the query assoc, as another variable such as row, and echo $row['image'] in a td. This will add a new td with the image for every entry in the database. Then echo your closing tags for the tr and table.
$query = mysql_query("SELECT image FROM table_name");
$query_a = mysql_fetch_assoc($query);
echo "<table><tr>"
foreach ($query_a as $row)) {
echo "
<td>" . $row['image'] . "</td>
";
}
echo "</tr></table>";
Not tested, but try something like this
<table>
<?php
// make sure there is at least 1 row first
$cnt = 0;
$while($row = mysql_fetch_assoc($query))
{
if(++$cnt == 1) {
echo '<tr>';
} elseif($cnt % 7 == 0) {
echo '</tr><tr>';
}
// show images in <td>'s
echo "<td>" . $row['image']. "</td>";
}
echo '</tr>';
?>
</table>
Keep it simple:
Query the database to get the desired information, loop through the results, construct a new row come each new loop.
$sql = "Select * from table";
mysql_query($sql) or die(mysql_error());
if(mysql_num_rows !=0)
{
// Found at least one record, create table
echo "<table>";
echo "<tr>";
while($row = mysql_fetch_assoc($sql)
{
$cell_count = 0;
// Create a new row for each record found
echo "<td>" . $row['image_column']. "</td>";
$cell_count++;
if($cell_count == 7)
{
echo "</tr>";
echo "<tr>";
$cell_count = 0;
}
}
// Close the table
echo "</tr>";
echo "</table>";
}
