所以我有一个导入,虽然通过一个excel文件循环并获取行并将其添加到数据库.

现在我要尝试的是查找该行的最后一个列中是否有图像.

并非所有行都有图像,这不是必需的.

我已尝试使用此处所述的解决方案Retrieving image in PHPExcel

但这会得到所有图像.如果不是每一行都有图像,这将是不好的.我不知道哪个图像属于哪一行.

任何帮助将不胜感激

解决方法:

我可以使用以下脚本进行操作.

if ($_FILES['file_source']['tmp_name']) {   

        // Get our import file extension
        ${'Extension'} = strtolower(array_pop(explode('.', $_FILES['file_source']['name'])));

        // Store our content array
        ${'Accounts'} = array();

        if (${'Extension'} == 'xls' || ${'Extension'} == 'xlsx') {

            // Create a new Excel instance
            if (${'Extension'} == 'xlsx') {
                $objReader = PHPExcel_IOFactory::createReader('Excel2007');
            } else {
                $objReader = PHPExcel_IOFactory::createReader('Excel5');
            }
            $objReader->setReadDataOnly(false);
            $objPHPExcel = $objReader->load($_FILES['file_source']['tmp_name']);
            $objWorksheet = $objPHPExcel->getActiveSheet();

            // Check for the columns and column titles
            if($objPHPExcel->getActiveSheet()->getCellByColumnAndRow(0, 1)->getValue() != 'Post Title' || $objPHPExcel->getActiveSheet()->getCellByColumnAndRow(1, 1)->getValue() != 'Content' || $objPHPExcel->getActiveSheet()->getCellByColumnAndRow(2, 1)->getValue() != 'Link' || $objPHPExcel->getActiveSheet()->getCellByColumnAndRow(3, 1)->getValue() != 'Link Title' || $objPHPExcel->getActiveSheet()->getCellByColumnAndRow(4, 1)->getValue() != 'Link Description' || $objPHPExcel->getActiveSheet()->getCellByColumnAndRow(5, 1)->getValue() != 'Image'){
                echo json_encode(array('response'=>'fail', 'reason'=>'column_error'));
                exit;   
            }

            // Get the total number of rows in the spreadsheet
            $rows = $objWorksheet->getHighestRow();

            // Check that each row contains all the required data
            $row_errors = 0;
            $row = 1;
            // skip the first row if it has our column names
            for (((($objPHPExcel->getActiveSheet()->getCellByColumnAndRow(0, $row)->getValue()) == 'Post Title') ? $row = 2 :  $row = 1); $row <= $rows; ++$row) {

                // Sanitize all our & add them to the accounts array
                if($objPHPExcel->getActiveSheet()->getCellByColumnAndRow(0, $row)->getValue() == '') { $row_errors++; }
                if($objPHPExcel->getActiveSheet()->getCellByColumnAndRow(1, $row)->getValue() == '') { $row_errors++; }

            }

            if($row_errors>0){
                echo json_encode(array('response'=>'fail', 'reason'=>'required_data'));
                exit;   
            }

            // Loop through all the rows (line items)
            $row = 1;
            ${'Iterator'} = 0;

                ${'Accounts'}[${'Iterator'}] = array('Post Title'       => inputCleanSQL($objPHPExcel->getActiveSheet()->getCellByColumnAndRow(0, $row)->getValue()),
