Replace previous/next by images

Postby Tata » Sat Apr 09, 2016 12:15 pm

How shall be coded the replacement of next/previous word/character by an image?
I have placed images into the template

Code: Select all

                <table width="100%" cellspacing="0" cellpadding="0" border="0">
                    <tr>
                        <td class="previous">
                            <?php echo tag('img src="'.$pth['folder']['templateimages'].'previous.png" alt="'.$tx['navigator']['previous'].'"');?>
                        </td>
                        <td class="top">
                            <a href="#TOP" title="<?php echo $tx['navigator']['top'];?>"><?php echo tag('img src="'.$pth['folder']['templateimages'].'top.png" alt="'.$tx['navigator']['top'].'"');?>
                        </td>
                        <td class="next">
                            <?php echo tag('img src="'.$pth['folder']['templateimages'].'next.png" alt="'.$tx['navigator']['next'].'"');?>
                        </td>
                    </tr>
                </table>
but the alt attribute doesn't work and I don't know how to link the image to next/previous function.

That is supposed to work; you may need to escape special HTML characters, though:

Code: Select all

<?php echo tag('img src="'.$pth['folder']['templateimages'].'previous.png" alt="'.XH_hsc($tx['navigator']['previous']).'"');?>

Indeed, that's somewhat a problem. Most likely it's best to make a copy of the functions previouspage() and nextpage() and place them directly in the template under another name; adjust these functions and call them instead of previouspage()/nextpage(). (Not ideal, but supposed to work.)

Code: Select all

function tpl_previouspage()
{
    global $tx;

    $index = XH_findPreviousPage();
    if ($index !== false) {
        return a($index, '" rel="prev" alt="' . $tx['navigator']['previous']) . tag('img src="userfiles/images/flags/de.gif"') . '</a>';
    }
}

function tpl_nextpage()
{
    global $tx;

    $index = XH_findNextPage();
    if ($index !== false) {
        return a($index, '" rel="next" alt="' . $tx['navigator']['next']) . tag('img src="userfiles/images/flags/de.gif"') . '</a>';
    }

BTW: using the default supplied language texts as alt text is not correct, in my opinion, because the alt text is supposed to describe the image, but not its function. I would use the default texts as title, and add some descriptive text for the alt attribute.

THX, that's it. However, on 2lang it seems not to work. I tried to change the code by

Code: Select all

function tpl_previouspage()
{
    global $tx; $pth;

    $index = XH_findPreviousPage();
    if ($index !== false) {
        return a($index, '" rel="prev" alt="' . $tx['navigator']['previous']) . tag('img src="'.$pth['folder']['templateimages'].'previous.png" class="prev"') . '</a>';
    }
}

function tpl_nextpage()
{
    global $tx;

    $index = XH_findNextPage();
    if ($index !== false) {
        return a($index, '" rel="next" alt="' . $tx['navigator']['next']) . tag('img src="'.$pth['folder']['templateimages'].'next.png"') . '</a>';
    }
}
 
But the previous, next icons are not loaded and in their properties is:
http://localhost:8888/website/previous.png
but there should be
http://localhost:8888/warhol/templates/ ... evious.png

Nun, am Localhost funtioniert es. AN einer Subdomain an meinem Hostserver, aber nicht. Es würde wohl relative URL brauchen, oder?

Das habe ich gelösst. Diese Losung funktioniert aber nur für die Hauptsprache. Was soll da erweitert sein, um auch unter 2lang zu funtionieren?

Scheint ja bereits behoben zu sein :?

Ja. SO funktioniert es auch unter 2lang pages:

Code: Select all

    function tpl_previouspage()
    {
        global $tx, $pth;

        if ($index !== false) {
            return a($index, '" rel="prev" alt="' . $tx['navigator']['previous']) . tag('img src="'.$pth['folder']['userfiles'].'images/previous.png"') . '</a>';
        }
    }

    function tpl_nextpage()
    {
        global $tx, $pth;

        $index = XH_findNextPage();
        if ($index !== false) {
            return a($index, '" rel="next" alt="' . $tx['navigator']['next']) . tag('img src="'.$pth['folder']['userfiles'].'images/next.png"') . '</a>';
        }
    }

Now, while testing the iconized prev/next function, I see that the "next" works fine. But the "prev" returns always to the very first page. What may be the reason?

Turning the PC ON this morning, the "prev" icon works as expected 8-)

Fine. :)

Maybe OPcache was involved here, also.
