Adding linebreak on fpdf cells

问题

I must add a linebreak for my images to appear after each other. I have tried the following but it does not work.

$rs['imagepath'] = $imagepath;
    $pdf->Image("{$imagepath}\n");

The original code to output the images is below, but it outputs only the first index and the second and third images does not come up... :(

$rs['imagepath'] = $imagepath;
    $pdf->Image("{$imagepath}");

The result is in a foreach loop like this:

     foreach($select as $index => $rs) 
{    
        $rs['imagepath'] = $imagepath;
        $pdf->Image("{$imagepath}"); 
}

回答1:

You can use ln() function i think.you have to define every image in one line

$fpdf->ln();

回答2:

I think your code has a mistake, try the below code to iterate over the $rs array. in the current code, your $imagepath variable is always remain same. you can then print a \n characters to pdf for printing new lines

foreach($select as $index => $rs) 
{    
        $imagepath = $rs['imagepath'];
        $pdf->Image("{$imagepath}"); 
}

Edit: I found this on another stack overflow thread

If you are using fpdf, in order to be able to use line breaks you will need to use a multi-line text cell as described here.

If you use this, then line breaks in your text should be interpreted and converted correctly.

Just a quick example:

$pdf->Multicell(0,2,"This is a multi-line text string\nNew line\nNew line");

Here, 2 is the height of the multi-line text box. I don't know what units that's measured in or if you can just set it to 0 and ignore it. Perhaps try it with a large number if at first, it doesn't work.
