我想在输入值中显示旧的输入.如果没有旧输入，则显示其他变量:
value="{{ old('salary_' . $employee->id) or 'Default' }}"
But when there is no old input, it gives me 1 instead of the default value!
I think the problem has something to do with the concatenation, but I don't know how to fix it!?
or is a comparison operator in PHP, so your code is evaluating to true, or 1. What you want is a ternary if statement.
As mentioned, or can be used in blade as shorthand for a ternary if statement.
但您可以(也应该)将默认值作为第二个参数传递给函数，如下所示:
value="{{ old('salary_' . $employee->id, 'Default') }}"
