Converting HTML Table to a CSV automatically using PHP?

Answer 1

You can use this function in separate js file:

function exportTableToCSV($table, filename) {

        var $rows = $table.find('tr:has(td)'),

            // Temporary delimiter characters unlikely to be typed by keyboard
            // This is to avoid accidentally splitting the actual contents
            tmpColDelim = String.fromCharCode(11), // vertical tab character
            tmpRowDelim = String.fromCharCode(0), // null character

            // actual delimiter characters for CSV format
            colDelim = '","',
            rowDelim = '"\r\n"',

            // Grab text from table into CSV formatted string
            csv = '"' + $rows.map(function (i, row) {
                var $row = $(row),
                    $cols = $row.find('td');

                return $cols.map(function (j, col) {
                    var $col = $(col),
                        text = $col.text();

                    return text.replace('"', '""'); // escape double quotes

                }).get().join(tmpColDelim);

            }).get().join(tmpRowDelim)
                .split(tmpRowDelim).join(rowDelim)
                .split(tmpColDelim).join(colDelim) + '"',

            // Data URI
            csvData = 'data:application/csv;charset=utf-8,' + encodeURIComponent(csv);

        $(this)
            .attr({
            'download': filename,
                'href': csvData,
                'target': '_blank'
        });
    }

Now, to initiate this function, you can use:

$('.getfile').click(
            function() { 
    exportTableToCSV.apply(this, [$('#thetable'), 'filename.csv']);
             });

where 'getfile' should be the class assigned to button, where you want to add call to action. (On clicking this button, the download popup will appear) and "thetable" should be the ID assigned to table you want to download.

You can also change to the custom file name to download in code.
