Grid view php

[nlal]

Is it possible to create grid view in php?Or any thing equivalent to that?What i actually want is to query the database(mySQL) and print the result in a table form on the web page.
Any help would be appreciated....

The way I do this is that I sort my database results into array of arrays. Something like this:

$rez = array(array("a", "b", "c"), array("e", "f", "h"),  .............etc)

Now each row in the table is represented with one array in $rez. All you have to do now is to loop through all the element of $rez like this:

echo "<table>\n";
foreach($rez as $row){
     echo "<tr>\n";
     foreach($row as $td){
          echo "<td>\n";
          echo $td."\n";
          echo "</td>\n";
     }
     echo "</tr>\n";
}
echo "</table>\n";

Or you could just use 1 regular for loop.

$result = mysql_query("select * from `table`");
$maxColumns = 3;

echo '<table><tr>';
for ($currentColumn = 0; $data = mysql_fetch_object($result); $currentColumn++) {
  if ($currentColumn = $maxColumns) {
    echo '</tr><tr>';
    $currentColumn = 0;
  }

  echo '<td>' . $data->columnName . '</td>';
}
echo '</tr></table>'

Or u coud do it like this:

class Table{
    private $table_rows = array();
	private $width = "100%";

	public function setWidth($width){
		$this -> width = $width;
	}	
	/*use this function to add just one row to the table (good for looping)*/
	public function addRow($row){
		$this -> table_rows[] = $row;
	}	
	
	/*use this function if you have array of table rows*/
	public function setTable($table_rows){
		$this -> table_rows = $table_rows;
	}
	
	public function printT(){
		echo "<table width='".$this->width."'>\n";
		foreach($this -> table_rows as $row){
			echo "<tr>\n";
			foreach($row as $td){
			   echo "<td>\n";
			   echo $td."\n";
			   echo "</td>\n";
			}
			echo "<tr>\n";
		}
		echo "</table>\n";
	}

}

Now you can expand this class easily and use it over and over again.

$rez = array(array("a", "b", "c"), array("e", "f", "h"),  .............etc);

$table = new Table();
$table->setTable($rez);
$table->setWidth("50%"); //change table width if you want to
$table->printT();

But then you still need to give the data in the format of a 2D array. I think the OP wants to do this with database results, which naturally come one at a time. Thus, you need support for a 1D array.

class Table {
  private $data = array();
  private $columns;

  public function __construct($columns = 5, array $data = null) {
    $this->columns = (int)$columns;

    if ($data) {
      foreach ($data as $item) {
        $this->addItem($item);
      }
    }
  }

  public function addItem($item) {
    $currentRow = sizeof($this->data);

    if (!isset($this->data[$currentRow])) {
      $this->data[$currentRow] = array();
      $currentColumn = 0;
    } else {
      $currentColumn = sizeof($this->data[$currentRow]);

      if ($currentColumn >= $this->columns) {
        $this->data[++$currentRow] = array();
        $currentColumn = 0;
      }
    }

    $this->data[$currentRow][$currentColumn] = (string)$item;
  }
}

But my example supports 1D and 2D arrays in ... :)))

1D support in Table::addRow($ row) so basically you can do this:

$tb = new Table();
$link = mysqli_connect("localhost", "", "", "");

if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

$query = "SELECT * FROM some_table";

if ($result = mysqli_query($link, $query)) {

    while ($row = mysqli_fetch_row($result)) {
       $tb->addRow($row);
      /*
      or you can pick your table fields
      $tb->addRow(array($row[0], $row[1]));
      */
    }

    /* free result set */
    mysqli_free_result($result);
}

/* close connection */
mysqli_close($link);
/*and echo your table out*/
$tb->printT();

You are assuming that the OP was asking for a way to output the columns of the database table as columns of the output table. When the OP stated that he wanted a "grid" view, I assumed that he meant he wanted each row of the database table as an entry in the grid.

Personally, I'd prefer using a list to approach the creation of a grid, but my post was simply to put yours into perspective.

Here's how to use a list:

CSS:

ul.grid li {
  float: left;
  width: 64px;
  height: 64px;
  margin: 8px;
  border: 1px solid #000000;
}

HTML:

<ul class="grid">
  <li><a href="#">Grid Item #1</a></li>
  <li><a href="#">Grid Item #2</a></li>
  <li><a href="#">Grid Item #3</a></li>
  <li><a href="#">Grid Item #4</a></li>
  <li><a href="#">Grid Item #5</a></li>
</ul>

PHP:

echo '<ul class="grid">';

while ($data = mysql_fetch_object($result)) {
  echo '<li><a href="' . $data->link . '">' . $data->title . '</a></li>';
}

echo '</ul>';

Well, now he/she has choice :))
