html - Fatal error: Can't use function return value in write context in views/stock/form.php on line 29 -


my code working fine in localhost , when upload server, show error on spesific line. error line of code.

<input type="text" required="required" name="i_name" class="form-control" placeholder="masukkan nama item..." <?php if(!empty(trim($row->item_name))){ ?> value="<?= $row->item_name ?>"<?php } ?> />

that's because using empty() on trim() function.

try trim() before passing data empty() function, this:

<?php $item_name=trim($row->item_name); ?> <input type="text" required="required" name="i_name" class="form-control"    placeholder="masukkan nama item..." <?php if (!empty($item_name)) { echo 'value="' . $row->item_name . '"'; } ?> />

also, if me, recommend using cleaner code:

<?php $item_name=trim($row->item_name); $value=''; if(!empty($item_name)){     $value='value="'.$row->item_name.'"'; } ?> <input type="text" required="required" name="i_name" class="form-control" placeholder="masukkan nama item..." <?=$value;?> />

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer
