Problema na geração do pdf

[damiaojr91]

Boa noite pessoal, tudo bem?

Sou iniciante em desenvolvimento e estou com um projeto em Laravel que utilizará o JasperPHP-OpenBoleto, porém estou tendo problemas para gerar os pdfs... Recebo a seguinte mensagem ao tentar gerar com o arquivo de exemplo itauJasperA4.php:

`TypeError: strpos(): Argument #1 ($haystack) must be of type string, array given in file /var/www/vendor/tecnickcom/tcpdf/tcpdf.php on line 12134

Poderiam por gentileza me dar uma luz quanto a instalação, ou com algum vídeo, ou documentação um pouco mais detalhada para eu poder entender melhor?

Agradeço desde já.

Boa noite, estou virando um projeto que utiliza esta lib para gerar boletos do Itaú, até então o projeto rodava em PHP 7.4 com o Laravel na versão: 8.83.23. Até então utilizando a lib JasperPHP-OpenBoleto apontando para a master tudo funcionava bem para gerar o boleto, porém ao rodar meus testes para atualizar para ultima versão do Laravel (9.45.1) e para o PHP 8.1.13, cai no mesmo erro que você.

Obtive alguns retornos de códigos que estão depreciados para o PHP 8.1 e por isso em breve devo fazer um fork/pr deste repositório para poder contribuir com a comunidade, porém para poder tentar te ajudar, segue uma maneira simples e paliativa para utilizar esta biblioteca com as versões atualizadas do PHP e do Laravel:

Depois que o Composer instalar as dependências busque pelo arquivo: JasperPHP/PdfProcessor

E altere os seguintes trechos de códigos:

Busque por:

public function RoundedRect($arraydata) {
        if ($arraydata['mode'] == 'Transparent')
            $style = '';
        else
            $style = 'FD';
        //
        //        JasperPHP\Pdf::$pdfOutPut->SetLineStyle($arraydata['border']);
        JasperPHP\Instructions::$objOutPut->RoundedRect($arraydata["x"] + JasperPHP\Instructions::$arrayPageSetting["leftMargin"], $arraydata["y"] + JasperPHP\Instructions::$y_axis, $arraydata["width"], $arraydata["height"], $arraydata["radius"], '1111', $style, $arraydata['border'], $arraydata['fillcolor']);
    	//draw only border
	if(isset($arraydata['border']['width']) && $arraydata['border']['width']>0){		
		JasperPHP\Instructions::$objOutPut->SetLineStyle($arraydata['border']);
		JasperPHP\Instructions::$objOutPut->RoundedRect($arraydata["x"] + JasperPHP\Instructions::$arrayPageSetting["leftMargin"], $arraydata["y"] + JasperPHP\Instructions::$y_axis, $arraydata["width"], $arraydata["height"], $arraydata["radius"], '1111',$arraydata['border']);		
		JasperPHP\Instructions::$objOutPut->SetLineStyle(array());
	}
    }

E substitua por:

public function RoundedRect($arraydata) {
        if ($arraydata['mode'] == 'Transparent')
            $style = '';
        else
            $style = 'FD';
        //
        //        JasperPHP\Pdf::$pdfOutPut->SetLineStyle($arraydata['border']);
        JasperPHP\Instructions::$objOutPut->RoundedRect($arraydata["x"] + JasperPHP\Instructions::$arrayPageSetting["leftMargin"], $arraydata["y"] + JasperPHP\Instructions::$y_axis, $arraydata["width"], $arraydata["height"], $arraydata["radius"], '1111', $style, $arraydata['border']['width'], $arraydata['fillcolor']);
    	//draw only border
	if(isset($arraydata['border']['width']) && $arraydata['border']['width']>0){
		JasperPHP\Instructions::$objOutPut->SetLineStyle(['width' => intval($arraydata['border']['width'])]);
		JasperPHP\Instructions::$objOutPut->RoundedRect($arraydata["x"] + JasperPHP\Instructions::$arrayPageSetting["leftMargin"], $arraydata["y"] + JasperPHP\Instructions::$y_axis, $arraydata["width"], $arraydata["height"], $arraydata["radius"], '1111',$arraydata['border']['width']);
//		JasperPHP\Instructions::$objOutPut->SetLineStyle(array());
	}
    }

E depois busque por:

    public function Line($arraydata) {
        $this->print_expression($arraydata);
        if ($this->print_expression_result == true) {
           //var_dump($arraydata["style"]);
            //echo ($arraydata["x1"] + JasperPHP\Instructions::$arrayPageSetting["leftMargin"])."||". ($arraydata["y1"] + JasperPHP\Instructions::$y_axis)."||". ($arraydata["x2"] + JasperPHP\Instructions::$arrayPageSetting["leftMargin"])."||". $arraydata["y2"] + JasperPHP\Instructions::$y_axis."||". $arraydata["style"]; 
            
            JasperPHP\Instructions::$objOutPut->Line((int)$arraydata["x1"] + JasperPHP\Instructions::$arrayPageSetting["leftMargin"], (int)$arraydata["y1"] + JasperPHP\Instructions::$y_axis, (int)$arraydata["x2"] + JasperPHP\Instructions::$arrayPageSetting["leftMargin"], (int)$arraydata["y2"] + JasperPHP\Instructions::$y_axis, $arraydata["style"]);
        }
    }

E substitua por:

public function Line($arraydata) {
        $this->print_expression($arraydata);
        if ($this->print_expression_result == true) {
           //var_dump($arraydata["style"]);
            //echo ($arraydata["x1"] + JasperPHP\Instructions::$arrayPageSetting["leftMargin"])."||". ($arraydata["y1"] + JasperPHP\Instructions::$y_axis)."||". ($arraydata["x2"] + JasperPHP\Instructions::$arrayPageSetting["leftMargin"])."||". $arraydata["y2"] + JasperPHP\Instructions::$y_axis."||". $arraydata["style"];
            $arraydata["style"]['width'] = intval($arraydata["style"]['width']);
            JasperPHP\Instructions::$objOutPut->Line((int)$arraydata["x1"] + JasperPHP\Instructions::$arrayPageSetting["leftMargin"], (int)$arraydata["y1"] + JasperPHP\Instructions::$y_axis, (int)$arraydata["x2"] + JasperPHP\Instructions::$arrayPageSetting["leftMargin"], (int)$arraydata["y2"] + JasperPHP\Instructions::$y_axis, $arraydata["style"]);
        }
    }

O PHP 8 em diante está restritivo em relação a operações matemáticas com inteiros e strings (como deve realmente ser), "Unsupported operand types: string * int" e isso acontecia devido a lib do tcpdf utilizar as entradas de $arraydata["style"]['width'] para fazer uma multiplicação interna, mas neste valor vai uma string, gerando o erro.

Espero ter ajudado!
