[phplib] Extension of table class From: Jens Benecke (jens <email protected>)
Date: 09/04/00

Hi,

for a database project I did some extensions to the table() class. Perhaps
there is enough interest to clean them up a little and put them into the
main phplib tree.

Hyperlinks in table cells
~~~~~~~~~~~~~~~~~~~~~~~~~
First, table_cell is rewritten to allow hyperlinks to another document,
appending the current column name and the current value as parameters. For
example, in a column called "ID" a table cell would not look like

                523a
but like
                <a href="details.php?ID=523a">523a</a>

if the array $make_links contained an ID element with the value
"details.php".

This is the replacement method:
---------------------------------------------------------------------------
class MyTable extends Table {
# var $map_links = array();

        function table_cell($row, $col, $key, $val, $class="") {
                $this->table_cell_open($class);
                if(isset($this->make_links[$key])) {
                        # Es gibt schon einen Parameter an der URL dran -> "?"->"&"
                        if(ereg("\?", $this->make_links[$key])) {
                                $c = "&";
                        } else {
                                $c = "?";
                        }
                        printf("<a href=\"%s\">%s</a>",
                                $this->make_links[$key].$c.$key."=".$val, $val);
                } else {
                    printf("%s", $val);
                }
                $this->table_cell_close($class);
        }
---------------------------------------------------------------------------

New method for labeling the checkboxes that are optionally placed in the
first column of a table row. I did this because I needed to know the
(database) ID of the table row, not the number of the shown table row. So I
set the counting element in "<input type=checkbox>" to something more
sensible: The current value of the table column whose name is in
$col_count. (which would ideally be a number or some sort of short ID.)

This enables me to put a submit button that "filters" selected table rows
out of the lot.

---------------------------------------------------------------------------
        function table_checkbox_cell($row, $row_key, $data, $class="") {

                if(isset($this->col_count)) {
                        $x = $data[$this->col_count];
                } else {
                        $x = $row;
                }

                if ($this->check) {
                        printf(" <td%s><input type=\"checkbox\" name=\"%s[%s]\" value=\"%s\"></td>\n",
                        $class?" class=$class":"",
                        $this->check,
                        empty($data[$this->check])?$row_key:$data[$this->check],
                        $x);
                }
        }
---------------------------------------------------------------------------

Suggestions welcome, as always... ;)
