I am new to PHP, so I want the while loop the result every times is different because I fetch data from CSV file, so it should not be all the data is same.
This is my code
<div style="margin: 1%">
<?php
//include 'barcode128.php';
require 'vendor/autoload.php';
if (($csvfile = fopen($_FILES['file']['tmp_name'], "r")) !== FALSE) {
while (($csvdata = fgetcsv($csvfile, 1000, ",")) !== FALSE) {
$colcount = count($csvdata);
if($colcount!=5) {
$error = 'Column count incorrect';
} else {
/*$product = $csvdata[0];
$product_id = $csvdata[1];
$rate = $csvdata[2];
$description = $csvdata[3];
$image = $csvdata[4];
$imageData = base64_encode(file_get_contents($image));
echo '<div class="wrapper">';
echo '<div class="a"><img src="data:image;base64,'.$imageData.'" width="50"/>
<div><b>Item: '.$product.'</b></div>
<div><svg id="barcode"><script>JsBarcode("#barcode", "'.$product_id.'",{
format: "code128",width: 1,height: 35,fontOptions: "bold",marginRight:30});</script></svg></div><span><b>Price: '.$rate.' </b></span><div><span><b>Desc: </b>'.$description.'</span></div></p></span>
</div></div>';
*/
$imageData = base64_encode(file_get_contents($csvdata[4]));
echo '<div class="wrapper">';
echo '<div class="a"><img src="data:image;base64,'.$imageData.'" width="50"/>
<div><b>Item: '.$csvdata[0].'</b></div>
<div><svg id="barcode"><script>JsBarcode("#barcode", "'.$csvdata[1].'",{
format: "code128",width: 1,height: 35,fontOptions: "bold",marginRight:30,font:"arial"});</script></svg></div><span><b>Price: '.$csvdata[2].' </b></span><div><span><b>Desc: </b>'.$csvdata[3].'</span></div></p></span>
</div></div>';
}
}
fclose($csvfile);
}
?>
</div>
The result of the current code: image-result
The CSV file: image-csv
This is what I want the result: enter image description here
So, how can I make the result can loop every times and break it, then loop the next data from the CSV file? Thank you
The problem is that you are creating multiple svg elements with the same id. You are then using this single id in your JsBarcode() call. By doing this, the Javascript will always act on the first element with this id.
To remedy this, we must create elements with unique ids, and then use this unique id in each Javascript call.
Since you have $product_id = $csvdata[1]; in your commented-out code, this answer is going assume that $csvdata[1] is unique per row.
Inside of your echo, change
<div><svg id="barcode"><script>JsBarcode("#barcode", "'.$csvdata[1].'",{
to
<div><svg id="barcode_'.$csvdata[1].'"><script>JsBarcode("#barcode_'.$csvdata[1].'", "'.$csvdata[1].'",{
