Question

我将变量从控制器传递到刀片中。这是我来自控制器的代码：

$offerConditionsData = Offercondition::where('offerId', $id)->where('deleted', '0')->get();
return view('Administrator.offers.add', $data);

我在刀片文件的顶部定义了一个变量：

@if(isset($offerConditionsData))
@foreach ($offerConditionsData as $offerConditions)
@php $selectedCondCheckbox = $offerConditions->keyword;
@endphp
@endforeach
@endif

如果我回显$ selectedCondCheckbox，那么我找到了以下内容：

customer_get_discounts_and_special_offers_on_certain_product_or_categories

现在我希望如果变量值与常量匹配，则会选中正确的复选框。以下是刀片文件中的代码，用于选中一系列复选框中的复选框。

<input type="radio" name="condition_tab" value="1" class="flat-red" style="position: absolute; opacity: 0;" @php if(isset($selectedCondCheckbox) == 'customer_get_discounts_and_special_offers_on_certain_product_or_categories') { echo "checked=checked"; } else { echo ""; } @endphp>

<input type="radio" name="condition_tab" value="2" class="flat-red" style="position: absolute; opacity: 0;" @php if(isset($selectedCondCheckbox) == 'discount_on_total_amount_of_shipping') { echo "checked=checked"; } else { echo ""; } @endphp>

但是，我看到第二个复选框已被选中。它应该检查第一个复选框作为php变量的值，与常量匹配。

你的if条件确实存在一些错误

单独尝试条件

#include <stdio.h>
#include <ctype.h>

char c;

char num (char c);

int main () {
    int sum;

    printf("Enter a word:");

    c=0;

        while (c=getchar() != '\n') {
            c=toupper(c);
            sum+=c;
        }

    printf("Scrabble value : %d",sum);

    return(0);
}

char num (char c) {

    if (c=='A'||c=='E'||c=='I'||c=='L'||c=='N'||c=='O'||c=='R'||c=='S'||c=='T'||c=='U') c=1;
    if (c=='D'||c=='G') c=2;
    if (c=='B'||c=='C'||c=='M'||c=='P') c=3;
    if (c=='F'||c=='H'||c=='V'||c=='W'||c=='Y') c=4;
    if (c=='K') c=5;
    if (c=='J'||c=='X') c=8;
    if (c=='Q'||c=='Z') c=10;

    return(c);
}

Answer 2

尝试使用此代码

<input type="radio" name="condition_tab" value="1" class="flat-red" style="position: absolute; opacity: 0;" {{ isset($selectedCondCheckbox) ? $selectedCondCheckbox == 'customer_get_discounts_and_special_offers_on_certain_product_or_categories' ? 'checked=checked' :'' :'' }} >

<input type="radio" name="condition_tab" value="2" class="flat-red" style="position: absolute; opacity: 0;" {{ isset($selectedCondCheckbox) ? $selectedCondCheckbox == 'discount_on_total_amount_of_shipping' ? 'checked=checked' :'' :'' }}>
