生成不同文本图像的问题

Question

I'm creating a student ID card system, where each student will have his/her own.

For this I am using the intervention image, to pick up the student data and put in the standard ID card template.

The basic code for this I did was:

<?php

[...]

$card = Image::make('card_id-model.png');

$card->text('CARD ID', 20, 40, function($font) {
    $font->file('arial.ttf');
    $font->size(24);
    $font->color('#fdf6e3');
    $font->align('center');
    $font->valign('top');
    $font->angle(45);
});

$card->text('NAME: STUDENT\'S NAME', 20, 60, function($font) {
    $font->file('arial.ttf');
    $font->size(24);
    $font->color('#fdf6e3');
    $font->align('center');
    $font->valign('top');
    $font->angle(45);
});

$card->text('CODE: STUDENT\'S CODE', 20, 80, function($font) {
    $font->file('arial.ttf');
    $font->size(24);
    $font->color('#fdf6e3');
    $font->align('center');
    $font->valign('top');
    $font->angle(45);
});

$card->save('card_id - student\'s code.png');

This way is slower, considering that I will call the function every time I create the image. So I decided to instantiate the image first, since it will be used for all card id. Well, but I'm experiencing problems applying it in a loop to generate several at the same time since the texts are overwriting.

<?php

[...]

$card = Image::make('card_id-model.png');

$card->text('CARD ID', 20, 40, function($font) {
    $font->file('arial.ttf');
    $font->size(24);
    $font->color('#fdf6e3');
    $font->align('center');
    $font->valign('top');
    $font->angle(45);
});

for ($students as $student) {
    $card->text('NAME: ' . $student->name, 20, 60, function($font) {
        $font->file('arial.ttf');
        $font->size(24);
        $font->color('#fdf6e3');
        $font->align('center');
        $font->valign('top');
        $font->angle(45);
    });

    $card->text('CODE: ' . $student->code, 20, 80, function($font) {
        $font->file('arial.ttf');
        $font->size(24);
        $font->color('#fdf6e3');
        $font->align('center');
        $font->valign('top');
        $font->angle(45);
    });

    $card->save('card_id - ' . $student->code . '.png');
}

That was the best and quickest way I found to mass-generate. Anybody got any tips?

Answer 1

i usually do a design first in AI, then get the SVG out of it, then fill in with CSS+HTML. Since PHP can help filling it in, i use it to generate the HTML only.

Then the HTML will be transformed to PDF and then i just print it from there.

In any case, PHP is not ideal to generate images eventhough there's a way to do it. Use Browser's power to do it. Google Chrome is robust, but if you need it to be runable on server, you can use wkhtmltopdf.
