edit:
Need to have an extra column in the barcodes sectionthat would display the barcode image.How do i go about customising?
Hi
I have tried to add this to v12, and followed all instructions step by step including reviewing your screenshots to ensure there are no mistakes, but this is not working when I create a new item.
Assuming I need to enter the item code, item name, item group and then some number in the item_barcode_gener field, the barcode should be generated. Am I right ?
Would love your guidance on this.
@danishaak No need to enter value in barcode_gener this value we set as 1 before form save please check script cur_frm.save()
And this value just for checking barcode already generated or not
Please share your script we will check…
What version is this for ?
ERPNext version12
Am trying it on 11 …not working
Is there anything stopping it from working on 12 ?
Hi Mahendra,
Thanks for replying.
Please find code below:
`frappe.ui.form.on('Item','validate', function(frm) {
var cur_doc = frm.doc;
frappe.model.set_value(cur_doc.doctype, cur_doc.name, "custom_bar_code", cur_doc.item_code);
if (cur_doc.custom_barcode_gener === 0) {
if(cur_doc.custom_bar_code){
$(frm.fields_dict['custom_barcode_image'].wrapper).html('<svg id="code128"></svg>');
$.getScript("/assets/frappe/js/lib/JsBarcode.all.min.js", function( data, textStatus, jqxhr ) {
JsBarcode("#code128", cur_doc.custom_bar_code, {
height: 40,
width: 2,
fontSize: 11,
flat: true,
background: "#FFFFFF"
});
var svg = $('#code128').parent().html();
frappe.model.set_value(cur_doc.doctype, cur_doc.name, "custom_barcode_svg", svg);
frappe.model.set_value(cur_doc.doctype, cur_doc.name, "custom_barcode_gener", 1);
cur_frm.save();
});
} else
{
frappe.msgprint(__("Please enter Barcode to to be printed"));
}
}
});`
Hi Everybody

Thanks and Regards

Hey there,
I have a related problem. I have a base64 encoded image in a hidden field in my doc. When I use print this picture is being shown. But if i press PDF it dissapears.
Why?
Can someone help in generating a new barcode as soon as the item is saved like getting a button click to generate barcode?
